Gastric emptying, hepatobiliary studies, liver and spleen studies are collectively termed

• A. Cardiac NM Studies
• B. Health Physicist
• C. Radiation Safety Officer
• D. Gastrointestinal NM Studies

Answer: (D)

These procedures are all nuclear medicine tests focused on the gastrointestinal tract and surrounding abdominal organs, using radiotracers to visualize function and anatomy. Gastric emptying measures how quickly the stomach empties to assess motility. Hepatobiliary studies track bile flow from the liver through the biliary system, often evaluating gallbladder function and drainage. Liver and spleen scans examine tracer uptake in the liver and spleen as part of abdominal imaging. Taken together, they form Gastrointestinal NM Studies because they center on GI tract function and related abdominal imaging, unlike cardiac nuclear medicine studies or roles like Health Physicist or Radiation Safety Officer, which are not imaging study categories.
