Patient Information for Neuroradiology CT Scan

What is a CT scan?

CT (computed tomography) or CAT scan is a specialized x-ray machine producing pictures that look like slices. Most patients find a CT scan to be a relatively simple test. You will be asked to lay on a table that moves in and out of a donut-type opening.

How should you prepare for a CT scan?

Patients who have CT scans of the head or neck often are asked to stop eating for about two hours before the study. Intravenous contrast is often used to enhance the images.

What if I am pregnant?

As with any x-ray procedure you should consult your doctor if you think you may be pregnant to determine if the CT scan can be postponed until the birth of your child. If you are pregnant and you must have a CT examination, please inform the technologist so that adequate steps of protection can be taken.

Should I take my medicine?

You should continue to take your regular medications before and after the CT scan.

How long does a CT scan take?

A CT scan is rapid examination. It varies from a few minutes to up to 1/ 2 hour.

When do I find out the results?

The CT images are reviewed and interpreted by a radiologist. A report will be dictated, typed, and sent to the physician that referred you for the study. He/she will contact you to discuss the findings and what to do next.
