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

13N-NH3 Myocardial Perfusion Imaging (Slides)

Pdf Summary

This document is a summary of a module on Cardiac PET Myocardial Perfusion Imaging. The module contains several case studies related to the use of Ammonia N-13 in PET imaging. The first case involves a 48-year-old female who experienced chest tightness. The rest/Lexiscan stress N13-NH3 myocardial perfusion PET study was performed, and the findings were evaluated using visual estimation of coronary artery calcium from low-dose CT AC scans. The second case involves a 72-year-old female with chest tightness. A rest/adenosine stress N13-NH3 myocardial perfusion PET study was performed, and the patient experienced chest pain and dyspnea during the adenosine infusion. The third case involves a 69-year-old male with exertional chest pain. A rest/dipyridamole N-13 NH3 stress myocardial perfusion PET study was performed, and no change in heart rate or blood pressure was observed with adenosine, indicating a possible caffeine ingestion. The fourth case involves a 58-year-old male with central chest pain and exertional shortness of breath. A rest/Lexiscan N-13 NH3 stress myocardial perfusion PET study was performed, and the patient underwent coronary artery bypass graft surgery. The fifth case involves a 69-year-old female with chest pain and mildly elevated troponin. A rest/Lexiscan N-13 NH3 stress myocardial perfusion PET study was performed, and the patient was found to have non-obstructive coronary artery disease. The document concludes with a summary of the advantages of cardiac PET/CT and the usefulness of quantitative flow assessment in diagnosing various conditions.
