Patient Motion During Cardiac PET Imaging

Cardiac PET perfusion imaging has been gaining acceptance in the nuclear cardiology community because of higher diagnostic accuracy, faster protocols for patient convenience, lower radiation exposure, and less artifact resulting in fewer false positive studies. Despite these advantages, patient motion during the PET acquisition does occur and can lead to an inconclusive or false positive result. This discussion will describe how it occurs, the appearance of motion on images, and the potential impact on interpretation.
