Module 12. Interpretation and Reporting of Cardiac PET Myocardial Perfusion Studies-Interpretation and Reporting of Cardiac PET Myocardial Perfusion Studies (Presentation)

Video Transcription

Video Summary

The video features Dr. Andrew Crean, a cardiologist at the University of Ottawa Heart Institute, who discusses interpreting and reporting PET myocardial perfusion studies. He acknowledges the assistance of Dr. Ali Peddarazadeh in preparing the presentation. Dr. Crean explains that PET is a different technology from SPECT imaging, as it allows for quantitative assessment of absolute myocardial blood flow, which improves the accuracy and precision of diagnosing ischemia. He recommends following the reporting structure provided by the American Society of Nuclear Cardiology (ASNC) and emphasizes the importance of a clear and well-structured imaging report that is comprehensible to non-experts and becomes part of the patient's medical record.<br /><br />Dr. Crean highlights the necessary information to include in a PET study report, such as hospital details, patient demographics, indication for the test, medication information, stress agent and tracer used, and any relevant prior cardiac testing. He discusses the interpretation of relative perfusion images, including the extent and severity of perfusion defects and abnormal LV function. He also explains the value of quantitative PET findings, particularly myocardial blood flow reserve and coronary vascular resistance, in assessing coronary artery disease (CAD) and identifying microvascular disease. Dr. Crean advises on the measurement and interpretation of myocardial blood flow, including the use of splenic switch-off and adjusting for high resting flow. He concludes by explaining the importance of consistency in measurement protocols and providing a comprehensive and concise conclusion in the imaging report.<br /><br />The video provides valuable information and guidance for interpreting and reporting PET myocardial perfusion studies and underscores the importance of clear communication between radiologists and referring physicians.
