HCPCS 78814

Positron emission tomography (PET) with concurrently acquired computed tomography (CT) for local attenuation correction and anatomical localization imaging; limited area (eg, chest, head/neck)

AI EXPLANATION: A limited-area PET-CT scan combines two advanced imaging technologies into a single appointment focused on a specific part of the body, such as the head, neck, or chest. A positron emission tomography (PET) scan uses a small amount of a radioactive tracer to detect cellular and metabolic activity, while a computed tomography (CT) scan takes detailed cross-sectional X-ray pictures of bones and soft tissues. Merging these images allows healthcare providers to see both the physical structure and the biological function of tissues in a targeted region.
