Which procedure is a x-ray of the gallbladder?

• A. Cholecystogram
• B. Ultrasound of gallbladder
• C. X-ray of the pancreas
• D. Endoscopic examination of the bile ducts

Answer: (A)

The test is about imaging the gallbladder using X-ray with contrast. A cholecystogram, also called cholecystography, is the procedure that outlines the gallbladder on X-ray after a contrast agent is given. This shows the gallbladder’s size, shape, and how it fills, helping detect stones or other abnormalities.

Ultrasound uses sound waves, not X-rays, to visualize the gallbladder, so it isn’t an X-ray procedure. An X-ray focused on the pancreas targets a different organ. Endoscopic examination of the bile ducts visualizes the ducts via an endoscope with fluoroscopy, not a straightforward X-ray image of the gallbladder itself.
