Positron emission tomography (PET) imaging; whole body

AI EXPLANATION: A whole-body positron emission tomography (PET) scan is an advanced diagnostic imaging examination that evaluates the metabolic activity and cellular function of organs and tissues throughout the entire body. Before the scan, a small amount of a radioactive tracer is introduced into the body, which highlights areas where cells are actively consuming energy. A specialized scanner then detects these signals to produce detailed three-dimensional images that help physicians detect, evaluate, and monitor conditions such as cancers, infections, or inflammatory disorders.
