Gallbladder scan - cholecystogram: A cholecystogram is an x-ray procedure used to help evaluate the gallbladder. For the procedure, a special diet is consumed prior to the test and contrast tablets are also swallowed to help visualize the gallbladder on x-ray. The test is used to help in diagnosing disorders of the liver and gallbladder, including gallstones and tumors.

Gallbladder radionuclide scan: performed by injecting a tracer (radioactive chemical) into the bloodstream. A gamma camera is used to perform the scan. The camera will detect the gamma rays being emitted from the tracer, and the image of where the tracer is found in the organs is transmitted to a computer. This test is very good for detecting acute infection (cholecystitis) or blockage of a bile duct. It is also helpful in determining whether there is rejection of a transplanted liver.
