Positron emission tomography (PET) imaging; skull base to mid-thigh

AI EXPLANATION: A PET scan from the skull base to the mid-thigh is a specialized imaging test that evaluates cellular activity across the neck, chest, abdomen, and pelvis. After a small amount of a safe radioactive tracer is administered, the scanner detects areas where cells are actively absorbing the tracer. This helps clinicians identify, stage, or monitor conditions such as cancers, infections, or inflammatory disorders by showing how tissues and organs are functioning at a metabolic level.
