Arm CT Scan

An arm CT scan is a medical imaging study used to diagnose the medical conditions of the arm. It is also called computed tomography (CT) scan or computed axial tomography (CAT). This imaging procedure uses X-rays to acquire images of the affected area in the arms.

Preparation for Arm CT Scan

There is no special preparation involved for arm CT scan. However, if you are undergoing ultrasound with contrast material, your provider may give you special instructions.

Procedure for Arm CT Scan

In order to start the procedure, you will be asked to lie on a table that is made to slide in and out of a large, donut-shaped machine. The table then slowly slides inside the machine, and the X-ray beam will take several images of your arm from different angles. You will need to hold your breath for a few seconds while the scan is being done. The actual procedure is painless and usually takes around 30 minutes.
