Which imaging study images the gallbladder?

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

Answer: (A)

The main idea is imaging a specific organ with a targeted study. To visualize the gallbladder, the imaging study used is cholecystography, also called a cholecystogram. It involves giving contrast that fills the bile ducts and gallbladder so the gallbladder’s size, shape, and any stones or obstructions can be seen on X-ray. The other terms describe different ways of taking X-ray images (views or angles) rather than a study aimed at imaging the gallbladder itself. A projection, axial, or tangential refers to how the body is positioned or the direction of the X-ray beam, not to a gallbladder-specific imaging study.
