Positron emission tomography (PET) with concurrently acquired computed tomography (CT) for local attenuation correction and anatomical localization imaging; whole body

AI EXPLANATION: A whole-body PET-CT scan is an advanced imaging procedure that combines positron emission tomography (PET) and computed tomography (CT) in one visit. A small amount of a safe radioactive tracer is introduced into the body to highlight cellular activity and metabolism, while the CT component captures cross-sectional pictures of internal organs and structures. Combining these images provides healthcare providers with a comprehensive view of both the physical structure and functional activity of tissues throughout the entire body.
