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

In this video, Dr. Andrew Crean, a cardiologist at the University of Ottawa Heart Institute, discusses the interpretation and reporting of PET myocardial perfusion studies. He begins by acknowledging Dr. Ali Peddarazadeh for assisting in creating the presentation. Dr. Crean explains that PET is a preferred method for assessing myocardial perfusion due to its ability to quantify absolute myocardial blood flow. He highlights the limitations of conventional SPECT tracers, such as technetium, which underestimate disease severity and extent. He emphasizes the importance of structured reporting in delivering clear and concise information that is comprehensible to non-experts and becomes a part of the patient's medical record.<br /><br />Dr. Crean outlines the required information to be included in the imaging report, such as demographic data, primary indication, patient medications, and relevant prior cardiac testing. He discusses the importance of accurately reporting stress agents, tracers, and hemodynamic parameters during the test. Additionally, he explains the process of qualitative assessment of relative perfusion images and reporting abnormalities of perfusion, wall thickness, and myocardial function.<br /><br />The video further delves into the benefits of quantifying myocardial blood flow using PET, such as improving diagnostic and prognostic assessments and identifying coronary microvascular disease. Dr. Crean provides insights into interpreting and reporting quantitative PET findings, considering global flow, per-vessel flow, and segmental flow values. He also discusses the relevance of myocardial blood flow reserve and its interpretation in clinical practice.<br /><br />Throughout the video, Dr. Crean emphasizes the importance of consistency in measurement techniques, accurate image alignment, and proper region of interest placement. He presents clinical examples and offers recommendations for reporting myocardial blood flow measurements to ensure clear communication with referring physicians.<br /><br />In conclusion, Dr. Crean provides an overview of key points for an effective reporting structure and emphasizes the need for concise, well-structured reports that convey expertise and help guide patient management decisions. He encourages further education and recommends participating in PET workshops to enhance understanding and practice in PET imaging.
