Abstract
“Hot” artifacts affecting the chest wall can result from “contamination” due to radiopharmaceutical extravasation at the injection site, splatter from blood, urine or injectate, or nearby radioactive sources (such as another patient on the treadmill) detected by the gamma camera. Brown adipose tissue is avid for MPI radiopharmaceuticals and may be present in the supraclavicular regions. “Cold” attenuation artifacts can result from superficial jewelry or implantable devices (e.g., pacemakers), or the patient’s arms positioned alongside the chest wall during image acquisition.
