Answer 1

PET scan is an imaging test that uses an IV tracer to identify disease in organs and tissues.

Step-by-step explanation:

PET scan, which stands for Positron Emission Tomography, is an imaging test that uses an IV tracer to identify disease in organs and tissues. It involves injecting a radioactive substance into the patient's bloodstream, which then emits gamma rays when collected in the appropriate area of the body. A PET scanner, working together with a computer, detects these emissions and generates special pictures that provide details on both the structure and function of various organs.
