Patient Motion During Cardiac PET Imaging.

Cardiac PET imaging is increasingly used for myocardial perfusion studies because of its high diagnostic accuracy and low radiation exposure to the patient. However, patient motion can be challenging, affecting a large number of studies. Motion artifacts can lead to inconclusive or false-positive results, complicating clinical interpretation. This article explores the causes of motion artifacts and their characteristic appearance in cardiac PET imaging, highlighting their distinction from true perfusion abnormalities. Strategies for minimizing motion through effective patient positioning and communication are discussed. Understanding and addressing motion artifacts are crucial for optimizing diagnostic accuracy and ensuring the full benefit of cardiac PET imaging.
