Which statement describes scintigraphy information?

• A. Functional information
• B. Anatomical information
• C. Mechanical information
• D. Thermal information

Answer: (A)

Scintigraphy provides functional information about tissues and organs. It uses radiopharmaceuticals to track physiological processes like blood flow, metabolism, or receptor activity, so the resulting images reflect how organs are working rather than their exact structure. For instance, bone scans show areas of increased metabolic activity in bone, and heart perfusion imaging reveals how well heart muscle is functioning. Sometimes scintigraphy is combined with CT to pinpoint location, but the core data come from function, not detailed anatomy.
