Overview of CT Scans

CT stands for computerized tomography. A CT scan combines many x-ray images to create a three-dimensional picture of your tissues and bones. Doctors often request CT scans over x-rays because CT scans give them more details about the inside of your body. CT scans are also called CAT (computerized axial tomography) scans.

You can receive a CT scan of any part of your body. The process is quick and painless. Your doctor will help you decide if CT is right for you.

About CT Technology

A CT scanner is a donut-shaped tube with an x-ray that rotates around a patient. There are beams and detectors, which measure the amount of radiation absorbed by your body. The x-ray takes pictures from different angles, each an individual slice of your body. A computer combines these images to create a cross-sectional image, which can then be interpreted by a radiologist.

Uses of CT Scans

CT imaging is one of the most accurate tools for examining tissue. People of all ages can receive a CT scan. Your healthcare provider might order a CT scan to determine the location of a tumor or certain health condition. CT scans also help diagnose muscle and bone disorders. They can monitor the effectiveness of treatments, detect internal injuries, and guide surgical procedures. These are only a few of the various uses for CT scans.

Preparing for a CT Scan

Your doctor will give you individualized instructions about how you should prepare for your CT scan. You should plan on arriving early to the imaging center. Some CT scans require you to avoid eating or drinking in the four hours before your scan. Continue to take all of your regular medications unless otherwise directed.

Wear comfortable clothing to your appointment. It might be necessary for you to change into a gown when you arrive. You will be asked to remove any metal objects that may interfere with the scan: zippers, jewelry, hearing aids, piercings, etc.
