Question

Quizplus · Accepted Answer

The diagnostic technique that involves the use of radiopharmaceuticals to produce images of internal organs and tissues is called a nuclear scan. This can be done with various types of equipment, including single-photon emission computed tomography (SPECT) and positron emission tomography (PET) scanners. Radiographs (A) use X-rays, MRIs (B) use magnetic fields and radio waves, X-rays (D) use electromagnetic radiation, and ultrasound (E) uses high-frequency sound waves - none of which involve the use of radiopharmaceuticals.
