Nuclear Medicine involves:

Nuclear Medicine involves:

• A. imaging with ultrasound
• B. MRI-based anatomy imaging
• C. imaging with X-rays to form images
• D. a diagnosis of disease by the administration of a radioactive material (isotope)

Answer: (D)

Nuclear Medicine uses radiopharmaceuticals administered to the patient to evaluate physiology and function. The tracer’s distribution reflects metabolic activity in organs, and detectors pick up the radiation it emits to create images that show how an area is functioning, not just how it looks structurally. This functional information is different from other imaging methods: ultrasound relies on sound waves to image anatomy, MRI uses magnetic fields and radiofrequency to visualize soft tissues, and standard X-ray imaging forms pictures of structures using ionizing radiation. In practice, a nuclear medicine study might show how well the heart muscle is perfused or how a bone is metabolizing tracer, helping diagnose disease based on the radioactive material’s behavior in the body.
