Myocardial Viability with PET Clinical Data (Slides)

Pdf Summary

In Part 6, Module 14 of the document, the focus is on myocardial viability assessment with PET imaging. The module begins with an introduction to concepts such as ischemia, viability, hibernation, and scar. It explains the role of 18F-FDG PET imaging in assessing myocardial viability and how the data obtained from these scans can be used in diagnosis. The module also discusses various 18F-FDG PET viability protocols, including patient preparation and image acquisition. <br /><br />The module then presents two patient cases. In patient 1, a 54-year-old female with a history of coronary artery disease (CAD) and recurrent chest pain, various tests and assessments are discussed. In patient 2, a 70-year-old female with a total proximal LAD occlusion and reduced left ventricular ejection fraction (LVEF), the feasibility of opening the occluded artery is considered. <br /><br />The module also touches on the criteria for using 18F-FDG cardiac PET for viability assessment, emphasizing patients with normal LVEF, CAD without targets for revascularization, and those with normal or abnormal LVEF but normal coronary arteries. It also provides a decision-making algorithm for patients with EF <40%. <br /><br />Further sections of the module discuss patient preparation for PET imaging, highlighting standardization techniques for glucose loading in non-diabetic patients and insulin use in diabetic patients. Image acquisition and display, including the representation of perfusion and 18F-FDG uptake, are also discussed. The module concludes with interpretations based on various findings on the PET scans and provides recommendations based on these interpretations.
