CT Scans

CT or "CAT" scans are special tests that produce images of the body using X-rays and a computer. CT scans are powerful tools that provide very detailed pictures of your body to help establish a diagnosis.  CT scans are frequently used to evaluate the brain, neck, spine, chest, abdomen, pelvis and sinuses.

The CT scanner looks like a large donut with a narrow table. The patient lies on the table as it moves  through the center of the machine.  The CT technologist will perform the scan from the next room and will be able to see and speak with you at all times.

Some exams require a contrast or dye to be injected into a vein during the scan.

The time to complete a CT scan depends on what body parts are being examined and whether you are required to have an injection of contrast. Although the actual scanning time on the table takes less than a minute, patients should plan on 15 to 45 minutes for their appointment. After the scan is finished, a board certified radiologist will interpret the study and send a report to the referring physician.
