Module 09. How to Perform an 18F FDG Viability Study-How to Perform an 18 F-FDG Viability Study (Presentation)

Video Transcription

Video Summary

In this video, Dr. Gary Small and Dr. Christian Vifols discuss how to perform an FDG viability study as part of the PET curriculum produced by ASNC. They outline the learning objectives, which include preparing patients for the study, optimizing FDG administration, acquiring and processing cardiac viability images, interpreting image patterns and findings, and explaining the components of a viability study report.<br /><br />They explain that viability imaging is important in managing patients with left ventricular dysfunction due to coronary artery disease, as it can determine if LV systolic impairment is reversible. Viability imaging uses myocardial glucose metabolism as a marker of viable myocardium and is accomplished using FDG as a tracer for glucose utilization.<br /><br />The doctors discuss the physics and protocols of PET imaging, including the use of radionuclide tracers and coincidence detection. They also detail the patient preparation process, which involves standardizing the substrate environment by loading the patient with glucose after fasting, to favor glucose metabolism.<br /><br />They provide case examples to illustrate the interpretation of perfusion and metabolism images, and emphasize the importance of assessing the extent and severity of matched or mismatched defects to distinguish viable from non-viable myocardium.<br /><br />The video concludes with recommendations for a comprehensive FDG-PET viability report, which includes patient information, study indication and techniques, findings, functional gated images, and a summary with guidance on the likely utility of revascularization.<br /><br />The video credits Dr. Gary Small and Dr. Christian Vifols for their contributions, and acknowledges ASNC for allowing them to present the teaching aid. It also suggests further reading of the ASNC imaging guidelines document and practice points for more information.
