Which imaging study focuses on the gallbladder?

• A. Cholecystogram
• B. Projection
• C. View
• D. Axial

Answer: (A)

The imaging study that targets the gallbladder is a cholecystogram (cholecystography). It uses a contrast agent to fill and outline the gallbladder on X-ray images, allowing visualization of gallstones, stones in the biliary ducts, or gallbladder dysfunction. The other terms describe general radiographic concepts about how an image is captured (the position or orientation of the body or image) and not a procedure focused specifically on the gallbladder. Modern practice often relies on ultrasound for gallbladder evaluation, but for this question, the study that concentrates on the gallbladder is the cholecystogram.
