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

13N-NH3 Myocardial Perfusion Imaging (Slides)

Pdf Summary

The document contains case reviews and learning objectives related to ammonia N-13 cardiac PET myocardial perfusion imaging. The cases presented include a 48-year-old female with chest tightness, a 72-year-old female with chest tightness, a 69-year-old male with exertional chest pain, and a 58-year-old patient with chest pain and shortness of breath. These cases demonstrate the use of PET imaging to assess myocardial blood flow and diagnose conditions such as coronary artery disease (CAD), microvascular disease, and endothelial dysfunction. The document also discusses the benefits of using quantitative flow assessments and the advantages of cardiac PET/CT imaging, including improved resolution and sensitivity, lower radiation exposure, and the ability to assess coronary flow reserve and metabolism. The cases highlight the importance of proper patient preparation and interpretation of PET viability studies. In addition, the document mentions the use of adenosine stress testing and its limitations in identifying adenosine responders. The cases also discuss the significance of myocardial flow reserve in assessing CAD and the role of cardiac PET MPI in comparison to SPECT imaging. Overall, the document showcases the utility of ammonia N-13 cardiac PET myocardial perfusion imaging in diagnosing and evaluating various cardiac conditions.
