About the Exam
The CT or CAT scan is a special kind of x-ray examination that uses a computer to produce very detailed cross-sectional pictures of the head and different body parts. Our CT scanner performs spiral scans, the newest and fastest scanning technology available.

CT scans are painless, and many patients relax enough to fall asleep while the scan is being done.

If you are pregnant or suspect you might be, discuss this with your physician before undergoing this procedure.

During the Exam

Head Scan
The x-ray technologist positions you on the examining table and secures your head in a head cradle. This prevents even slight movements that can blur the x-ray pictures. While the contrast solution is being administered, you may experience a temporary flush; this is very normal. The nurse, along with the radiologist, will monitor you closely. You will hear a whirring sound as the scan is performed. It is important to lie very still. The x-ray table may move slightly during the scan, but you may not even notice the change.

The entire procedure takes between 15 and 30 minutes.

Body Scan
Before starting the exam, the nurse or technologist may ask you to drink a contrast solution. The x-ray technologist positions you on the examining table. You may receive an injection of contrast solution (see Head Scan section). You will hear a whirring sound as the scan is performed and the table moves you between scans. You may be asked to hold your breath, but don’t worry—it would only be for a few seconds.

The entire procedure usually takes about 30 minutes.

After the Exam
The radiologist evaluates the results of your CT scan. If more information is needed, more scans are taken.

Rochester Radiology sends the results of your CT scan directly to your physician so she or he can make a diagnosis and explain to you what the findings mean.
