Which term refers to studies examining gastric emptying, biliary function, and liver/spleen activity?

• A. Gastrointestinal NM Studies
• B. Cardiac NM Studies
• C. Lung NM Studies
• D. Thyroid Uptake Study

Answer: (A)

The main idea is gastrointestinal nuclear medicine studies, which use radiotracers to evaluate how the GI tract and related organs function. Gastric emptying measures how quickly the stomach empties its contents into the small intestine, typically by tracking a radiolabeled meal over time. Biliary function is assessed with hepatobiliary imaging, following tracer movement from the liver through the bile ducts to the gallbladder and intestine to evaluate flow and obstructions. Liver and spleen activity are also visualized in these scans to assess hepatic uptake and overall abdominal organ function. These aspects together define GI nuclear medicine studies, unlike cardiac, lung, or thyroid uptake procedures which focus on heart, lung, or thyroid function, respectively.
