CT scanners use x-rays and detectors that move around the body to take images of slices through the body. This technology has been in use since the 1970s.
Coral Gables Hospital has several types of CT scanners, including:
- Toshiba - Aquilion 64 Slice
- GE - Lightspeed 16 Slice
- TeraRecon Post Processing Workstation
(3D reconstruction and Angiography imaging)
Coral Gables' 64 Slice CT Scan is one of the fastest scanners available today. It takes multiple pictures of the body, allowing Radiologists to examine specific parts of the body in great detail. It can image everything from soft tissue and bone to muscles in a matter of seconds. Sometimes a small injection of a contrast agent is needed to get clear images of certain organs and vessels. If your scan requires a contrast agent, you will receive more details in the letter we send you confirming your appointment.
What is a CT or CAT scan?
A CT or CAT scan is a diagnostic imaging procedure that uses a combination of x-rays and computer technology to produce cross-sectional images (often called "slices") of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, blood vessels and organs. In computed tomography, the x-ray beam moves in a circle around the body.
This allows many different views of the same organ or structure, and provides much greater detail. The x-ray information is sent to a computer that interprets the x-ray data and displays it in 2-dimensional form on a monitor. In some cases, the data is sent to a special computer that produces 3D pictures.
CT scans may be done with or without contrast. "Contrast" refers to a substance taken by mouth or injected into an intravenous (IV) line that causes the particular organ or tissue under study to be seen more clearly. Contrast examinations require special preparation. CT scans may be performed to help diagnose tumors, evaluate blood vessels, determine calcium "scores" of the coronary arteries or check for other internal disease, injuries or damage.
Preparing For Your CT Scan
No preparation is needed for most CT scans. Sometimes, an injection of a contrast agent that contains iodine is needed. This is injected right before the CT scan, and is usually well-tolerated by patients. If you have any allergies, please call us to discuss these with our physician before your exam.
