CPT® Code 78814

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

The CPT® Code 78814 refers to a specialized imaging procedure known as positron emission tomography (PET) combined with computed tomography (CT). This dual imaging technique is designed to enhance the accuracy of both functional and anatomical imaging. The PET scan focuses on visualizing soft tissue structures and provides insights into metabolic and chemical functions within the body. In contrast, the CT scan captures detailed images of both hard and soft tissue structures, allowing for a comprehensive view of the body's internal landscape. By fusing the images from these two modalities, healthcare professionals can obtain critical information about bone structures, organs, and any abnormal growths such as tumors. This combined approach is particularly beneficial in various clinical scenarios, including the staging of cancers, localization of seizure foci in the brain, and diagnosing infections or inflammatory conditions. Additionally, it serves as a valuable tool for ongoing surveillance of certain medical conditions. The procedure involves a careful administration of a radiolabeled isotope tracer through an intravenous line, which is essential for the PET scan. The imaging process is conducted with the patient positioned on an imaging table, ensuring optimal results. Following the PET scan, a CT scan is performed to provide further anatomical context, and the physician interprets the results, culminating in a comprehensive written report that details the findings from both imaging studies.
