How can a computed tomography (CT) scan help find the cause of pain?

ANSWER

Computed tomography (CT) scans help find the cause of pain by using X-rays and computers to produce an image of a cross-section of the body. During the test, you lie as still as possible on a table. It will move through a large, doughnut-shaped scanning device.

Your doctor may inject a solution into a vein before your scan. It can help make it easier to see what’s going on inside. Most CT scans take 15 minutes to an hour.
