Positron emission tomography (PET) with concurrently acquired computed tomography (CT) for local attenuation correction and anatomical localization imaging; skull base to mid-thigh

AI EXPLANATION: A PET-CT scan from the skull base to the mid-thigh is an advanced imaging examination that combines two types of scans into a single session. Positron emission tomography (PET) uses a safe, mildly radioactive tracer to highlight areas of active cellular metabolism, while computed tomography (CT) uses specialized X-rays to capture cross-sectional anatomical pictures of internal organs, bones, and tissues. Blending these images allows physicians to examine cellular activity and precisely locate abnormalities throughout the neck, chest, abdomen, and pelvis.
