How can a CT scan help in diagnosing gallstones?

A computed tomography (CT) scan may be used for detecting gallstones and examining the appearance of body parts surrounding the gallbladder. Gallstones are hard, pebble-like deposits that form in the gallbladder, the organ just below your liver and above your small intestine. The gallbladder stores bile, a fluid made by the liver, and then releases it into the small intestine when needed for aid in digesting fat from food.

Although ultrasound is the preferred test for detecting gallstones because it is 98% accurate, CT scans can help to evaluate the ducts leading in and out of the gallbladder, and spot any swelling in the gallbladder or pancreas. When used together, the two tests can give you a clearer picture of what is going on in your abdominal area so you and your doctor can decide on the best treatment plan for you.
