Radiopharmaceuticals are substances used in nuclear medicine. Which option lists the substance placed in such procedures?

• A. contrast media
• B. radiopharmaceuticals
• C. stents
• D. chemotherapy agents

Answer: (B)

In nuclear medicine imaging, a radiopharmaceutical is the substance placed into the patient. These are radioactive compounds designed to localize in specific tissues and emit radiation that our detectors can capture, producing images that reflect how the body functions rather than just its structure. Contrast media are used to enhance visibility in other imaging modalities like X-ray or CT but are not radioactive. Stents are implanted devices to keep vessels open. Chemotherapy agents are medicines used to treat cancer and are not imaging tracers.
