Excerpt

A 68-year-old male presented with chest pain, and a history of percutaneous coronary intervention to the right coronary artery. He had residual 80% stenosis in the mid left anterior descending artery (LAD). A dipyridamole rubidium-82 positron emission tomography (PET)–computed tomography (CT) myocardial perfusion imaging (MPI) study was performed to assess for ischemia in the LAD territory. Cardiac-gated stress images were reconstructed from the list-mode data using routine ECG-triggers. A separate respiratory-gated stress series was reconstructed using triggers that are routinely acquired using the RPM™ motion tracking system. Simultaneous dual-gated images were not reconstructed, nor needed to assess the respiratory motion as described herein. …
