About CT Scans

Computed Tomography (also known as CAT Scan, Computed Axial Tomography) is a technical advance over standard x-rays. A x-ray source and detector are moved about a focal plane in the body and a computer is used to generate an accurate cross-sectional image of the body. This powerful technique is used to evaluate pathology throughout the body. Administration of intravenous iodinated contrast aids in the evaluation of solid organ disease, for example metastatic lesions within the liver. Iodinated contrast may also be injected into the joints in the detection of ligament tears or other joint abnormalities.

What Does the Equipment Look Like?
The CT scanner is a large, square machine with a hole in the center, something like a doughnut. The patient lies still on a table that can move up or down, and slide into and out from the center of the hole. Within the machine, an x-ray tube on a rotating gantry (or frame) moves around the patient’s body to produce the images, making clicking and whirring noises as the arm moves. Though the technologist will be able to see and speak to you, you and the technologist will separated by a wall with a window.

How Does the Procedure Work?
Unlike conventional x-rays, which produce pictures of the shadows cast by body structures of different density, CT scanning uses x-rays in a much different way. In CT, numerous x-ray beams are passed through the body at different angles, and special sensors measure the amount of radiation absorbed by different tissues (and lesions such as a tumor). As you lie still, the scanner parts revolve around you (although you cannot see this happen), emitting and recording x-ray beams from as many as a thousand points on the circle. A special computer program then uses the differences in x-ray absorption to form cross-sectional images, or “slices,” of the head and brain. These slices are called tomograms, hence the name “computed tomography.”

How Should I Prepare for the Procedure?
You should wear comfortable, loose-fitting clothing for your CT exam. Anything that might interfere with imaging of the head—such as earrings, eyeglasses, dentures, dental implants, or hairpins—should be removed.

No special preparation is needed for a CT scan unless you are to receive a contrast material—a substance that highlights the organs and blood vessels and makes abnormalities easier to see. If the physician believes that an intravenous (IV) injection of a contrast material will be helpful, you will be asked in advance whether you have had allergies in the past or have ever had a serious reaction to medication. Many contrast materials contain iodine, which can cause such a reaction in persons who are allergic. If you have known allergies to other medications it may raise the possibility that you might have an allergic reaction to the contrast material. The radiologist also should know if you have asthma, multiple myeloma, or any disorder of the heart, kidneys, or thyroid gland, or if you have diabetes—particularly if you are taking Glucophage. Typically you will be asked to sign an “informed consent” form before having CT with injection of a contrast material.

Women should always inform their doctor or x-ray technologist if there is any possibility that they are pregnant. In some cases an alternate study will be performed to reduce or eliminate the radiation exposure to the fetus.

About MRI

Magnetic resonance imaging (MRI) uses radio-frequency waves and a strong magnetic field rather than x-rays to provide remarkably clear and detailed pictures of internal organs and tissues. The technique has proven very valuable for the diagnosis of a broad range of pathologic conditions in all parts of the body including cancer, heart and vascular disease, stroke, and joint and musculoskeletal disorders. MRI requires specialized equipment and expertise and allows evaluation of some body structures that may not be as visible with other imaging methods.

What are some common uses of the MRI procedure?
Because MRI can give such clear pictures of soft-tissue structures near and around bones, it is the most sensitive exam for spinal and joint problems. MRI is widely used to diagnose sports-related injuries, especially those affecting the knee, shoulder, hip, elbow and wrist. The images allow the physician to see even very small tears and injuries to ligaments and muscles.

In addition, MRI of the heart, aorta, coronary arteries and blood vessels is a fast, noninvasive tool for diagnosing coronary artery disease and heart problems. Physicians can examine the size and thickness of the chambers of the heart and determine the extent of damage caused by a heart attack or progressive heart disease.

Organs of the chest and abdomen—including the lungs, liver, kidney, spleen, pancreas and abdominal vessels—can also be examined in high detail with MRI, enabling the diagnosis and evaluation of tumors and functional disorders. MRI is growing in popularity as an alternative to traditional x-ray mammography in the early diagnosis of breast cancer. Because no radiation exposure is involved, MRI is often the preferred diagnostic tool for examination of the male and female reproductive systems, pelvis and hips and the bladder.

How should I prepare for the procedure?
Because the strong magnetic field used for MRI will pull on any ferromagnetic metal object implanted in the body, MRI staff will ask whether you have a prosthetic hip, heart pacemaker (or artificial heart valve), implanted port, infusion catheter, intrauterine device (IUD), or any metal plates, pins, screws or surgical staples in your body. In most cases surgical staples, plates, pins and screws pose no risk during MRI if they have been in place for more than four to six weeks. Tattoos and permanent eyeliner may also create a problem. You will be asked if you have ever had a bullet or shrapnel in your body or ever worked with metal. If there is any question of metal fragments, you may be asked to have an x-ray that will detect any such metal objects. Tooth fillings usually are not affected by the magnetic field but they may distort images of the facial area or brain, so the radiologist should be aware of them. The same is true of braces, which may make it hard to “tune” the MRI unit to your body. You will be asked to remove anything that might degrade MRI images of the head, including hairpins, jewelry, eyeglasses, hearing aids and any removable dental work.

The radiologist or technologist may ask about drug allergies and whether head surgery has been done in the past. If you might be pregnant, this should be mentioned. Some patients who undergo MRI in an enclosed unit may feel confined or claustrophobic. If you are not easily reassured, a sedative may be administered. Roughly one in 20 patients will require medication to reduce the anxiety associated with claustrophobia.

What does the MRI equipment look like?
The conventional MRI unit is a closed cylindrical magnet in which the patient must lie totally still for several seconds at a time.

How does the procedure work?
MRI is a unique imaging method because, unlike the usual radiographs (x-rays), radioisotope studies or even Computed Tomography (CT) scanning, it does not rely on ionizing radiation. Instead radiofrequency waves are directed at protons, the nuclei of hydrogen atoms, in a strong magnetic field. The protons are first “excited” and then “relaxed,” emitting radio signals that can be computer-processed to form an image. In the body, protons are most abundant in the hydrogen atoms of water—the “H” of H2O—so that an MR image shows differences in the water content and distribution in various body tissues. Even different types of tissue within the same organ, such as the gray and white matter of the brain, can easily be distinguished. Typically an MRI examination consists of two to six imaging sequences, each lasting two to 15 minutes. Each sequence has its own degree of contrast and shows a cross-section of the body in one of several planes (right to left, front to back, upper to lower).

How is the procedure performed?
The patient is placed on a sliding table and positioned comfortably for the MRI examination. Then the radiologist and technologist leave the room and the individual MRI sequences are performed. The patient is able to communicate with the radiologist or technologist at any time using an intercom. Also, many MRI centers allow a friend or, if a child is being examined, a parent to stay in the room. Depending on how many images are needed, the exam will generally take 15 to 45 minutes, although a very detailed study may take longer. You will be asked not to move during the actual imaging process, but between sequences some movement is allowed. Patients are generally required to remain still for only a few seconds to a few minutes at a time.

Depending on the part of the body being examined, a contrast material (usually gadolinium) may be used to enhance the visibility of certain tissues or blood vessels. A small needle connected to an intravenous line is placed in an arm or hand vein. A saline solution will drip through the intravenous line to prevent clotting until the contrast material is injected about two-thirds of the way through the exam.

When the exam is over the patient is asked to wait until the images are examined to determine if more images are needed. A radiologist experienced in MRI will analyze the images and send a report with his or her interpretation to the patient’s personal physician. This should take only a few days or less.

What will I experience during the MRI procedure?
MRI causes no pain but some patients can find it uncomfortable to remain still during the examination. Others experience a sense of being “closed in,” though the more open construction of newer MRI systems has done much to reduce that reaction. You may notice a warm feeling in the area under examination; this is normal but if it bothers you the radiologist or technologist should be notified.

If a contrast injection is needed, there may be discomfort at the injection site and you may have a cool sensation at the site during the injection. Most bothersome to many patients are the loud tapping or knocking noises heard at certain phases of imaging. Ear plugs may help.

About Ultrasound

Ultrasound imaging, also called ultrasound scanning or sonography, is a method of obtaining images from inside the human body through the use of high-frequency sound waves. The reflected sound wave echoes are recorded and displayed as a real-time visual image. No ionizing radiation (x-ray) is involved in ultrasound imaging. Obstetric ultrasound refers to the specialized use of sound waves to visualize and thus determine the condition of a pregnant woman and her embryo or fetus.

Ultrasound is a useful way of examining many of the body’s internal organs, including but not limited to the heart, liver, gallbladder, spleen, pancreas, kidneys and bladder. Because ultrasound images are captured in real time, they can show movement of internal tissues and organs and enable physicians to see blood flow and heart valve functions. This can help to diagnose a variety of heart conditions and to assess damage after a heart attack or other illness.

What are some common uses of the procedure?
Millions of expectant parents have seen the first “picture” of their unborn child with pelvic ultrasound examinations of the uterus and fetus. Ultrasound imaging is used extensively for evaluating the eyes, pelvic and abdominal organs, heart and blood vessels, and can help a physician determine the source of pain, swelling or infection in many parts of the body. Because ultrasound provides real-time images it can also be used to guide procedures such as needle biopsies, in which needles are used to sample cells from organs for laboratory testing. Ultrasound is now being used to image the breasts and to guide biopsy of breast cancer. Ultrasound is also used to evaluate superficial structures such as the thyroid gland and scrotum (testicles).

Doppler ultrasound is a special technique used to examine blood flow. Doppler images can help the physician to see and evaluate:

Blockages to blood flow (such as clots).
Narrowing of vessels (which may be caused by plaque).
Tumors and congenital malformation.
How should I prepare for the procedure?
You should wear comfortable, loose-fitting clothing for your ultrasound exam. Other preparation depends on the type of examination you will have. For some scans your doctor may instruct you not to eat or drink for as many as 12 hours before your appointment. For others you may be asked to drink up to six glasses of water two hours prior to your exam and avoid urinating so that your bladder is full when the scan begins.

What does the equipment look like?
Ultrasound scanners consist of a console containing a computer and electronics, a video display screen and a transducer that is used to scan the body. The transducer is a small hand-held device about the size of a bar of soap, attached to the scanner by a cord. The physician or technologist spreads a lubricating gel on the patient’s abdomen in the area being examined and then presses the transducer firmly against the skin to obtain images.

The ultrasound image is immediately visible on a nearby screen that looks much like a computer or television monitor. The physician or technologist watches this screen during an examination and captures representative images for storage. Often, the patient is able to see it as well.

How does the procedure work?
Ultrasound imaging is based on the same principles involved in the sonar used by bats, ships at sea and anglers with fish detectors. As the sound passes through the body, echoes are produced that can be used to identify how far away an object is, how large it is, its shape and its consistency (fluid, solid or mixed).

The ultrasound transducer functions as both a generator of sound (like a speaker) and a detector (like a microphone). When the transducer is pressed against the skin it directs inaudible, high-frequency sound waves into the body. As the sound echoes from the body’s fluids and tissues the transducer records the strength and character of the reflected waves. With Doppler ultrasound the microphone captures and records tiny changes in the sound wave’s pitch and direction of the sound. These echoes are instantly measured and displayed by a computer, which in turn creates a real-time picture on the monitor. The “live” images of the examination are usually recorded on videotape but one or more frames of the moving picture may be “frozen” to capture a still image.

How is the procedure performed?
The patient is usually positioned on an examination table. A clear gel is applied to the patient’s body in the area to be examined to help the transducer make secure contact with the skin. The sound waves produced by the transducer cannot penetrate air so the gel helps eliminate air pockets between the transducer and the skin. The technologist or radiologist presses the transducer firmly against the skin and sweeps it back and forth to image the area of interest.

When the examination is complete the patient may be asked to dress and wait while the ultrasound images are reviewed either on film or on a TV monitor. Often though, the technologist or radiologist is able to review the ultrasound images in real time as they are acquired and the patient can be released immediately.

What will I experience during the procedure?
Most ultrasound examinations are painless, fast and easy. You will lie on your back on an examining table. The technologist or doctor will spread some warm gel on your skin and then press the transducer firmly against your body, moving it until the desired images are captured. There may be varying degrees of discomfort from pressure as the technologist guides the transducer over your abdomen, especially if you are required to have a full bladder. The examination usually takes less than 30 minutes.

What are the limitations of General Ultrasound Imaging?
Ultrasound has difficulty penetrating bone and therefore can only see the outer surface of bony structures and not what lies within. For visualization of bone, other imaging modalities such as magnetic resonance imaging (MRI) may be selected.

Ultrasound waves do not pass through air; therefore an evaluation of the stomach, small intestine and large intestine may be limited. Intestinal gas may also prevent visualization of deeper structures such as the pancreas and aorta. Patients suffering from obesity are more difficult to image—this is because tissue attenuates (weakens) the sound waves as they pass deeper into the body.

About X-Ray & Digital Radiolography

Radiography, or as it is most commonly known, an x-ray, is the oldest and most frequently used form of medical imaging. Discovered more than a century ago, x-rays can produce diagnostic images of the human body on film or digitally on a computer screen.

X-ray imaging is the fastest and easiest way for a physician to view and assess broken bones, joint or spine injuries, chest and lung, and many other conditions. At least two images (from different angles) are taken and often three images are needed if the problem is around a joint (knee, elbow or wrist). X-rays also play a key role in guiding orthopedic surgery and in the treatment of sports-related injuries. X-ray may uncover more advanced forms of cancer in bones or soft tissue although early screening for cancer findings requires other methods.

To this end radiologists have developed alternative imaging methods that do not rely on

radiation, such as ultrasound and magnetic resonance imaging (MRI). However, because x-ray was the first imaging modality, many people (and medical imaging professionals) continue to use the term “radiology” to include all types of imaging. Strictly speaking, though, radiology refers to the use of x-rays.

How should I prepare for the procedure?
This procedure requires no special preparation. Women should always inform their doctor or x-ray technologist if there is any possibility that they are pregnant.

How does the procedure work?
Radiography involves exposing a part of the body to a small dose of radiation to produce an image of the internal organs. When x-rays penetrate the body, they are absorbed in varying amounts by different parts of the anatomy. The ribs and spine, for example, absorb much of the radiation and appear white or light gray on the image. Lung tissue absorbs little radiation and appears dark on the image. Depending upon the type of image-recording medium, chest x-rays can be maintained as hard-copy film for filing or, more commonly, as filmless digital images that are archived electronically. Digital images can also be transferred for storage onto CD-ROM. Stored images may be used to compare with later images if illness develops. Indeed, historical comparison films are often very important in the decision process as to whether a finding is clinically important or not.

How is the procedure performed?
Patients must remove their clothing, including undergarments that may contain metal. Most medical centers will give the patient a loose-fitting gown to wear. Patients will also be asked to remove all metallic jewelry that may interfere with the x-rays. Normally, a frontal or posteroanterior view is obtained, in which the patient stands with the body section pressed to the photographic plate, with hands on hips and elbows pushed in front in a somewhat exaggerated position. The technologist will ask the patient to be still and to take a deep breath and hold it. Breath-holding after a deep breath reduces the possibility of a blurred image and also enhances the quality of the x-ray image, since abnormalities in air-filled lungs are easier to see than in deflated lungs. Next, the technologist walks into a cubicle or small room to activate the radiographic equipment, which sends a beam of x-rays from the x-ray source behind the patient, through the patient’s chest, to the recording medium (film or digital cassette). Some equipment is designed to accommodate patients who cannot stand for chest x-rays.

The technologist may need to take additional views to properly see all parts of the chest or may take a side view, or lateral view, of the chest. For a lateral view, the patient stands sideways to the photographic plate with arms elevated, and the process is repeated. Views from other angles may be obtained if the radiologist needs to evaluate additional areas of the chest. Finally, a chest x-ray may be repeated within hours, days or months to evaluate for any changes. These repeated, sequential examinations are called serial chest x-rays.

When the chest x-rays are completed you will be asked to wait until the technologist checks the images for motion and makes sure that the entire chest is included. Ultimately, a radiologist will interpret the chest x-ray images using a lighted view box to review films or a computer and monitor to review digital images.

What will I experience during the x-ray procedure?
This is a painless procedure. The primary discomfort may come from the coldness of the recording plate. Individuals with arthritis or injuries to the chest wall, shoulders or arms may have discomfort trying to maintain position for the chest x-ray. In these circumstances, the technologist will assist you in finding a position that still ensures diagnostic image quality.

About Mammography

Screening types:
There are two types of screenings:

Routine Screening: Screening recommended on an annual basis for all women 40 years and older.
Diagnostic Screening: To visualize areas of concern following the detection of a lump, development of breast pain or nipple discharge.

Preparation for the Exam:
Discuss any new findings or problems in your breasts with your provider and inform him/her of any prior surgeries, hormone use, and family or personal history of breast cancer.
Wear a two-piece outfit to your screening with any easy to remove top.
Avoid wearing deodorants, powders or lotions in your breast area as these can appear as abnormalities.
Equipment Used:
Mammography X-ray Unit (a specially designed x-ray machine for viewing the breast from multiple angles).

What does the equipment look like?
Mammography machines are tall, rectangular x-ray devices which have a positioning platform that holds and compresses the breast so that images can be taken of all breast tissue at multiple angles.

What will I experience?
You will be given a paper vest to cover the upper portion of your body. It should be put on with the opening to the front.
Your breast will be placed on the mammography unit platform and compressed with a paddle (this is necessary to ensure that the machine is able to get quality x-rays or pictures of all the breast tissue from differing angles).
You will be asked to stay very still so as not to change the angle of your breast or blur the x-ray images.
It will take approximately 30 minutes to get all of the images that are needed.
How will I get the results of the test?
If a KDC provider has ordered your mammogram, you will receive your results either in a letter from the mammography department or by your provider.
If a non-KDC provider has ordered your mammogram, you will receive a letter containing the results of your exam from the mammography department.
Why should I have a mammogram?
Routine mammograms improve the odds that small abnormalities will be detected earlier. Early detection of these abnormalities increase the chance of diagnosing serious breast disease before it spreads to the lymph nodes or other parts of the body.

About Bone Density & DEXA Scans

What is osteoporosis?
Osteoporosis is a gradual loss of calcium that occurs in conjunction with structural changes resulting in thinner, more fragile bones which are more susceptible to fractures.

DEXA Scan:
DEXA (bone density screening) is most often used to diagnose osteoporosis and to determine an individual’s risk of developing fractures.

Risk Factors for osteoporosis:
Risk factors for osteoporosis include, but are not limited to:

Age
Body weight
History of prior fracture
Cigarette smoking
Excessive alcohol consumption
Usage of medications known to cause bone loss
Type I diabetes, liver disease, kidney disease or a family History of osteoporosis
Hyperthyroidism
Hyperparathyroidism
Preparation for the Exam:
Do not take calcium supplements for at least 24 hours prior to your exam
Wear loose, comfortable clothing without metal parts. You may be asked to wear a gown.
Do not schedule your DEXA scan within 14 days of a CT or any other procedure that required you to receive barium.
Notify your provider and the radiology technologist if you are pregnant.
Equipment Used:
Central DEXA

What will I experience?
You will be asked to lie on a padded table.
To view the spine, the legs are placed on a box to flatten the pelvis and lower the spine.
To view the hip, the foot is braced so that the hip is rotated inward.
You will be asked to remain as still as possible as the detector positioned above you slowly passes over each area to avoid producing blurred images.
The test lasts between 10-30 minutes.
How will I get the results of the test?
Follow-up with your primary provider to receive your results.

Why should I have a DEXA scan?
DEXA provides the most accurate data for diagnosing osteoporosis or estimating the risk for developing osteoporosis or osteoporosis related fractures.

Treatment Options:

Treatment options may include oral medications such as calcium supplements or other oral medications which can be ordered by your provider or infusions such as Reclast which may be administered by our Rheumatology Department.
