Quizplus · Accepted Answer

The combination of tomography and radioactive substances to produce enhanced images is known as positron emission tomography (PET). Fluoroscopy uses continuous x-ray beams to produce real-time images, therapeutic radiology is a treatment that uses high-energy radiation to kill cancer cells, and ultrasonic tomography uses high-frequency sound waves to produce images.
