How is a gallbladder scan performed?

The most common gallbladder scan is an ultrasound. This is done with a small probe that is gently scanned over your abdomen. The probe sends sound waves through the body and creates images using these sound waves. Your doctor or a technician can perform the ultrasound scan. It is not invasive and does not use radiation. Other scans include a computed tomography (CT) scan, which uses x-rays to scan the body and produce images, and a hepatobiliary iminodiacetic acid (HIDA) scan, which looks at how the gallbladder functions after you receive an injection of a drug that is taken up by the liver and gallbladder and then emptied into the intestines.
