Radiology Services


 Common radiology services include:
Ultrasound  |  CT Scan  |  Bone Scan  |  HIDA Scan  |  Lung Scan  |  Upper GI

 

Ultrasound

An ultrasound uses high-frequency sound waves to take images of the heart, digestive, reproductive or urinary tracts, or other soft tissue structures within the body. An ultrasound is also used to gather vital information and measurements of your unborn baby.

An ultrasound is a common, non-invasive, painless procedure used to investigate a wide variety of conditions. A hand-held device called a transducer is used to perform the ultrasound. The transducer slides slowly across your skin delivering images to the ultrasound monitor.

Abdominal Ultrasound can include imaging of the liver, gallbladder, pancreas, kidneys and aorta. You must not eat, drink or smoke from midnight the night before the exam, until the exam is complete.

Pelvic Ultrasound can include the examination of the uterus, overies, and bladder. You will be required to drink 32 ounces of water before your exam.

Vascular Ultrasound can include the examination of carotid, venous, arterial Doppler and echocardiogram. No special preparation is needed.

Thyroid, breast and testicle ultrasounds do not require special preparation.

Obstetrical or prenatal ultrasounds are used to gather important data on your growing baby. You may be able to see your baby's arms, legs, and head. You will be required to drink 16 to 32 ounces of water before this exam.

CT Scan

CT (or computerized tomography) is sometimes called a CAT scan. CT uses special x-ray equipment that gives doctors a better look at bones, blood vessels, organs, and tissues.

While regular x-rays show all of these areas, they are seen as overlapping each other. Regular x-rays are fine for diagnosing some health problems, but the CT scanner gives a more detailed picture because it makes an x-ray image of many very thin slices of a section of the body. With the help of a computer, these slices are put together to show a much better cross-section.

Doctors often use CT scans to help diagnose kidney, lung, liver, spine, and blood diseases; cancer, tumors, and cysts; as well as blood clots, hemorrhages and infections.

During a CT exam, you will lie down on a table. The part of your body to be studied will be moved into a large ring-like opening of the scanner. You will hear the sound of gears and motors as the equipment scans your body.

Some preparation is needed for certain scans.

Bone Scan

A bone scan is a radiology procedure that looks for abnormalities in the bones. A bone scan cal look at a particular joint or bone, or it can scan the whole body.

Common conditions leading to bone scan exams include any type of unusual bone pain, arthritis, stress fractures, infections in the bones, trauma, shin splints or cancer that can spread to the bone.

When you come into radiology for your appointment, you will receive an injection of a compound that localizes in the bone. In certain situations, imaging is performed at the time of injection. Otherwise, you can leave the department soon after the injections, and you will be asked to return two to three hours later for imaging. This is done to allow time for the injected compound to localize in your bones. Depending on the type of information desired, it takes 30 to 90 minutes to perform the scan.

No preparation is needed prior to your scheduled appointment.

HIDA Scan

The hepatobiliary scan is a radiology procedure that is done to evaluate bile drainage problems and to identify gallbladder problems including blocked, malfunctioning and diseased gallbladders. The scan also assists in determining if abdominal pain is related to gallbladder disease.

A hepatobiliary scan is sometimes done together with an ultrasound exam for a more complete evaluation.

During a hepatobiliary scan, you will receive an injection into a vein in your arm or hand. The injection will be followed by 60 minutes of imaging. During the scan, imaging cameras will be positioned over you. You may need to receive a second injection of a compound that helps the gallbladder show up better. This injection will be followed by 30 minutes of imaging. Or, you may receive an injection of a different compound that triggers your gallbladder to empty.

Some preparation is needed prior to your scheduled appointment.

Lung Scan

The lung scan is a radiology procedure that is used to determine the cause of shortness of breath or chest pain. It is most often used to evaluate possible life-threatening blood clots in the lungs. A blood clot may prevent normal blood flow to a part of a lung.

A lung scan can also be used to evaluate the flow of blood or air through the lungs and to evaluate the lung function of a patient before surgery.

There are two types of lung scans, a Ventilation scan and a Perfusion scan. Ventilation and Perfusion scans can be done separately or together to diagnose certain lung diseases. If both scans are done, the test is called a V/Q scan.

During a Ventilation scan, you will be asked to inhale a gas through a mask placed over your nose and mouth. A camera will take images of your lungs as you inhale and exhale the gas.

During a Perfusion scan, you will receive an injection into a vein that allows images to be taken of the blood flow to your lungs.

If the lungs are working normally, blood flow in a Perfusion scan matches air flow on a Ventilation scan. A mismatch between the Ventilation and Perfusion scans may indicate a pulmonary embolism.

Depending on the type of information needed, it takes 45 minutes to 1 hour to do the scan. No preparation is needed for the scan.

Upper GI with Small Bowel Follow Through

GI stands for gastrointestinal, commonly known as the digestive system. An Upper GI is an exam of the upper portion of your digestive system, including the esophagus, stomach, and small intestine.

Since the stomach and small intestine (bowel) cannot be seen well with just x-rays, an Upper GI with small bowel follow through exam requires the use of a liquid contrast medium. Traditional x-rays can only reproduce images of bone, the liquid contrast is used to show soft tissue in your body like your digestive tract.

During the exam, you will be asked to stand on a small platform. You will need to drink some liquid that will allow the radiologist to see your digestive tract on a special live x-ray called fluoroscopy. Next, the table will be tilted so you will be lying down. You may need to drink more liquid at this time. Your radiologist may need you to shift positions in order to see the stomach from various angles.

After the radiologist is finished with the examination, a technologist will take a series of stomach x-rays. Following the stomach x-rays, you will need to drink another glass of liquid, enough to coat the 22 feet of small bowel. You will need to wait 30 minutes and then have an x-ray to see how far the liquid has traveled. X-rays will be taken every 30 minutes until the entire small bowel has been seen and the liquid has passed into the large bowel. This step generally takes 60 minutes, but can take up to 2 to 3 hours for some. You will be informed of your progress throughout the exam.

Some preparation is needed for the procedure.
