Cardiac PET Advanced Virtual Workshop (December 7-8, 2024)-Clinical Value of Cardiac PET

Video Transcription
Video Summary
In the video, Dr. Dennis Calnon, a cardiologist in Columbus, Ohio, discusses the clinical value of Cardiac PET imaging. He highlights several factors that contribute to its clinical value, including its accuracy, efficiency, low radiation exposure, and unique information provided. <br /><br />Dr. Calnon emphasizes the unrivaled accuracy of Cardiac PET imaging, noting that it offers excellent image quality regardless of patient size or body composition. He explains that Cardiac PET has superior specificity due to robust attenuation correction and scatter correction, leading to accurate detection of myocardial tracer uptake. The higher myocardial extraction of the tracer in Cardiac PET allows for the detection of milder coronary artery disease, which may only slightly limit blood flow. Moreover, Cardiac PET is shown to be more accurate than SPECT imaging in detecting coronary artery disease in a meta-analysis study.<br /><br />The efficiency of Cardiac PET is highlighted, with Dr. Calnon explaining that the imaging procedure can be completed in just 20 to 23 minutes. This efficiency allows for late-day add-ons and reduces the overall cost of care. Additionally, Cardiac PET offers low radiation exposure, with studies showing that it falls well below recommended thresholds.<br /><br />The unique information provided by Cardiac PET is also discussed. This includes the measurement of left ventricular ejection fraction reserve, which has a high negative predictive value for excluding left main or three-vessel coronary artery disease. The measurement of myocardial blood flow reserve with Cardiac PET is considered a game-changer, as it allows for the integration of both macrocirculation and microcirculation effects on myocardial tissue perfusion. Dr. Calnon explains that myocardial blood flow reserve has diagnostic, prognostic, and patient management implications, especially in the detection of high-risk coronary artery disease.<br /><br />Furthermore, Cardiac PET has applications beyond coronary artery disease, such as myocardial viability assessment, evaluation of cardiac sarcoidosis, and detection of infections in prosthetic valves, LVADs, and pacemakers.<br /><br />In summary, Cardiac PET imaging offers high accuracy, efficiency, low radiation exposure, and unique information, making it a valuable tool in the field of nuclear cardiology.
