The __________ is administered to the patient

The __________ is administered to the patient

• A. Isotope
• B. Radiopharmaceutical
• C. Tracer
• D. Radioactive drug

Answer: (B)

In nuclear medicine, the substance given to the patient is a radiopharmaceutical. This term refers to a compound that combines a radioactive atom with a pharmaceutical molecule that directs it to a specific organ or physiological process, allowing targeted imaging or therapy. The radiopharmaceutical emits detectable radiation (like gamma rays or positrons) so the clinician can visualize or measure how a body part functions. This is different from just an isotope, which is only the radioactive nucleus without a targeting vehicle, and from a vague “tracer” or informal “radioactive drug” label, which aren’t the standard terms for the administered agent. Examples include technetium-99m radiopharmaceuticals used for bone or cardiac imaging and FDG for PET scans.
