Radiologists may provide fluoroscopic or ultrasonic guidance, radiation oncology treatments, nuclear medicine including the placement of ______, and other radiopharmaceutical therapies.

Radiologists may provide fluoroscopic or ultrasonic guidance, radiation oncology treatments, nuclear medicine including the placement of ______, and other radiopharmaceutical therapies.

• A. radiopharmaceuticals
• B. contrast media
• C. sutures
• D. antibiotics

Answer: (A)

In radiology, nuclear medicine uses radiopharmaceuticals—radioactive compounds designed to localize in specific tissues to enable imaging or therapy. These agents are placed into the patient (often under imaging guidance) to visualize function or to deliver targeted radiation. The other options aren’t radioactive agents used in nuclear medicine: contrast media are non-radioactive substances for enhancing imaging, sutures are surgical materials, and antibiotics are antimicrobial drugs. So the term that fits is radiopharmaceuticals.
