Case Review - Myocardial Blood Flow with 82Rb PET Imaging (Slides)

Pdf Summary

The document discusses several cases evaluated using PET MPI studies for chest pain assessment. In the first case, a normal perfusion scan with positive prognostic markers was observed in a 48-year-old female. In contrast, an 88-year-old male showed abnormal perfusion with adverse prognostic markers, indicating multivessel disease or severe endothelial dysfunction. Another case featured a 73-year-old female with abnormal perfusion and significantly reduced global myocardial flow reserve. A 62-year-old female exhibited large reversible defects in the LAD territory, while a 58-year-old male's test demonstrated normal perfusion but lack of EF augmentation, indicating non-responsiveness to Regadenoson. A 70-year-old male's study was deemed non-diagnostic due to significant motion artifacts. Lastly, a 52-year-old female with a history of COVID-19 presented with an ischemic defect in the LCx territory and wall motion abnormalities. The document highlights key markers for PET myocardial perfusion imaging, such as perfusion defect size, ejection fraction changes with stress, and myocardial blood flow reserve reduction. It also emphasizes the role of PET myocardial blood flow in distinguishing between single-vessel and multivessel disease, while cautioning against motion artifacts affecting accurate assessment.
