Computer Tomography (CT or CAT Scan)

Computer tomography combines a series of X-ray images taken from various angles to create a volume of data that can be processed to produce a three-dimensional image of a person’s body.

CT scans show bones and soft tissues inside the body. Medical professionals are able to view the images one by one or collectively as a comprehensive three-dimensional picture. The technique is very useful in allowing doctors to make decisions quickly.

A CT scan can be used to guide surgeons before complicated surgeries, locate internal damage, and to pinpoint where a disease, such as cancer, is located in the body.

What to expect during a CT Scan

Typical exams take10-15 minutes. Advanced Radiology’s multi-slice CT scanners are optimized to enhance image quality while reducing x-ray dose.

During a CT scan, you will lie on a table that will move through a doughnut-shaped tube. The tube will move around the area of your body to be scanned, collecting images from a variety of angles. You’ll be able to see out of both ends of the scanner. It’s normal to hear whirling or clicking noises during the scan.

The technician will ask you to relax and lie as still as possible, and may ask you to hold your breath for brief moments.

Sometimes, Iodine contrast will be administered to the patient intravenously, or orally, to make irregularities more clear to the scanner.

A CT scan will expose individuals to much higher levels of radiation than they would receive in a typical X-ray procedure. While radiation exposure can increase your risk of developing cancer, most doctors agree the benefits of a CT scan drastically outweigh the risk.

If you are pregnant, tell your doctor before participating in a CT scan.

How will I prepare for a CT Scan?

Do not eat or drink for 4 hours before exam. Some studies require an intravenous injection of contrast (x-ray dye).

If you are having a CT scan of the abdomen or pelvis, please call Advanced Radiology at (401/866) 727-4600 for instructions on preparation, since these studies may require a barium drink. This will provide more detail of your stomach and intestines).

For a better look at other areas, an intravenous (IV) contrast will be used. During an IV contrast scan, you may feel a warm sensation throughout your body, and possibly a metallic taste.

No preparation is necessary for a study of your spine, bones, joints, sinuses, or kidney stone studies.
