A client is scheduled for a cholecystogram. What is the diagnostic use of this exam?

• A. It visualizes the liver and pancreas.
• B. It visualizes the gallbladder and bile duct.
• C. It visualizes the biliary structures and pancreas via endoscopy.
• D. It shows the sizes of the abdominal organs and detects any masses.

Answer: (B)

The main idea here is that a cholecystogram is used to visualize the gallbladder and the biliary ducts to evaluate gallbladder-related disease. By giving a radiopaque contrast that fills the gallbladder through the biliary system, the study shows whether the gallbladder fills properly, empties normally, and whether there are stones, blockages, or structural abnormalities in the gallbladder and bile ducts. This helps diagnose conditions like gallstones, cholecystitis, or biliary obstruction. It does not primarily image the liver and pancreas, nor does it involve endoscopic visualization of the biliary system (that would be ERCP). It also isn’t a test that measures organ sizes or detects masses—that’s more in the realm of ultrasound or CT.
