Module 18. Case Review – 13N-NH3 Myocardial Perfusion Imaging-13N-NH3 Myocardial Perfusion Imaging (Presentation)

Video Transcription

Video Summary

The video discusses the protocols and findings of ammonia and rubidium PET rest stress myocardial perfusion imaging studies. These studies are used to assess myocardial blood flow and diagnose coronary artery disease. The video emphasizes the importance of properly fusing the images and obtaining a coronary artery calcium score. In the case studies presented, abnormal perfusion patterns were observed in patients with significant coronary artery disease. The video also highlights the advantages of cardiac PET over SPECT, including lower radiation exposure and improved spatial and temporal resolution. The use of quantitative flow assessment is discussed, which aids in the diagnosis of balanced ischemia, detection of microvascular disease, and assessment of transplant vasculopathy. The video concludes by summarizing the benefits of cardiac PET, such as increased diagnostic accuracy and the ability to assess viability, inflammation, and infection.
