Myocardial perfusion imaging; tomographic (SPECT), single study (including attenuation correction when performed), at rest or stress (exercise and/or pharmacologic), with or without quantification

The CPT® Code 78464 refers to myocardial perfusion imaging using tomographic techniques, specifically Single Photon Emission Computed Tomography (SPECT). This imaging procedure is designed to assess the blood flow to the heart muscle, which is crucial for diagnosing various cardiac conditions. During the procedure, a radioactive tracer is injected into the patient, which accumulates in areas of the heart that may not be receiving adequate blood supply. This accumulation indicates regions of the heart that are not functioning properly during the cardiac cycle. The SPECT camera captures these images, providing a detailed view of the heart's perfusion status. The imaging can be performed either at rest or during stress, which may be induced through exercise or pharmacologic agents. The inclusion of attenuation correction, when performed, enhances the accuracy of the images by compensating for any interference caused by surrounding tissues. This comprehensive approach allows physicians to evaluate the heart's function and identify potential issues related to coronary artery disease or other cardiac conditions.
