What is CT Scan?

Computed Tomography (CT), formerly known as a CAT scan, is a radiology technique that uses X-ray and computer equipment to produce cross-sectional images of body structures, tissues, and organs. CT imaging provides a unique ability to visualize soft tissue, bones, muscle, internal organs, and blood vessels.

Common Uses of CT

A CT scan can be used for a range of tests such as:

• Planning and proper administration of radiation treatments for tumors.
• Planning surgery.
• Quick identification of injuries to the liver, spleen, kidneys, spine, head, or other internal organs in cases of trauma.

Preventative Medical Screenings

CT scans are used to examine bones, organs, soft tissue, and blood vessels. Some areas that a CT scan is commonly used for are:

• CT Screening – Abdomen: Used to detect unsuspected abnormalities of liver, kidney, gall bladder, or adrenal glands.
• Stroke Screening
• CT Screening – Cardiac Scoring: Used to detect calcific plaque and help determine risk of coronary artery disease.
• CT Screening – Lung: Formal academic studies have documented potential value in detecting lung cancer at earlier stages, when the cancer can still be surgically removed.
• CT Screening – Pelvis: Used to detect asymptomatic, unsuspected abnormalities of bowel, ovaries, prostate gland, or bladder.
• Virtual Colonoscopy: CT is a non-invasive screening method for colon cancer and other bowel diseases.
• Revolution CT Scan: GE’s Revolution CT Scan is a high def, low dose option available at Southwest Diagnostic Imaging Center.

Patients should understand that many insurance companies do not reimburse for these screening examinations. All screening tests will be performed without the administration of intravenous or oral contrast. It is recommended that patients obtain a physician’s referral before scheduling these exams. Reports will be sent to the patient’s doctor, as well as directly to the patient. As with other screening tests, patients should understand that results may be inconclusive, and additional tests may be required. SWDIC does not recommend such screenings as substitutes for more comprehensive exams or studies.

What to Expect

A CT examination usually takes between five minutes and half an hour.

• The technologist will position you on the CT table. Pillows will be used to help you keep still in the proper position during the scan. The table will move slowly into the CT scanner opening. Depending on the area of the body being examined, the increments of movement may be very small and almost undetectable or large enough to feel the motion.
• To enhance the visibility of certain tissues or blood vessels, use of different contrast materials may be required. Depending on the type of examination, these materials may be injected through an IV, or oral contrast. Before receiving the contrast material, you should inform the technologist of the following:
  • Any allergies, especially to medications or iodine.
  • Any information regarding history of diabetes, asthma, kidney problems, heart, or thyroid conditions. These conditions may indicate a higher risk of reaction to the contrast material or potential problems with eliminating the material from your system after the exam.
• You will be alone in the room during your scan; however, you can communicate with your technologist at all times through an intercom system, and they will be able to see, hear, and speak with you throughout the entire exam.

What You Will Experience During This Exam

CT scanning is a painless procedure. Depending on the type of scan needed, individual preparations may differ. Here is an overview of what to expect from the different methods we use to administer contrast materials:
