A 19-year-old female asked:

Will a ct scan show gallstones/ other gall bladder problems as well as stomach ulcers? what about a urine and blood test?

Yes and no: Ct is fairly good at evaluating the gallbladder for stones or infection/inflammation. It is poor at evaluating the stomach for ulcers. This typically requires an upper endoscopy.

CT scan not best : A ct scan can can show gall stones but an ultrasound is a better imaging test for evaluation of the gallbladder. A ct scan might show a large gastric ulcer but an upper GI barium study or preferably an upper endoscopy is better to evaluate for gastric ulcers. Urinary tests are usually not helpful but liver function blood tests should always be done to evaluate for gall bladder disease.

Ct scan will show gallstones if calcified. And very few gallstones contain calcium , less than ten percent. Agree ultrasound is best study.

Possible: Gallstones may show on a ct scan but not always depending on the size and location and what they are made out of. Some stones are radiopaque (show on ct) and some don't depending mostly on the calcium concentration. Also, newer ct scans may show some signs of stomach ulcers but not the best study. An upper endoscopy (camera in the stomach) is better for that. No urine test for gb. Yes blood tests.
