Case review - Non-Perfusion Imaging – Sarcoidosis (Slides)

Pdf Summary

Dr. Panithaya Chareonthaitawee's module 20 presentation focuses on non-perfusion imaging for the detection of cardiac sarcoidosis. In the first part, he describes the characteristics of normal and abnormal uptake on images to detect cardiac sarcoid. Normal uptake includes no FDG uptake, while abnormal uptake can occur with or without RV involvement. Other possible findings include scar tissue, FDG uptake due to ICD lead, inadequate myocardial suppression, and isolated basal lateral wall FDG uptake. <br /><br />The second part of the presentation discusses characteristics of false positive studies. These may include insufficient metabolic preparation, ICD lead artifact, and nondiagnostic FDG study due to suboptimal myocardial suppression.<br /><br />The third part focuses on components of an appropriate report for cardiac sarcoid studies. These include a review of the medical record, confirmation of metabolic preparation, co-registration of PET and CT data, routine quality control steps, and the use of both normalized cardiac and hybrid nuclear medicine displays for image viewing.<br /><br />The presentation also provides information on the use of PET in diagnosing cardiac sarcoidosis, including specific criteria for histologic and clinical diagnosis. It also highlights the importance of adequate metabolic preparation prior to PET, such as following a high-fat, low-carbohydrate diet and avoiding exercise. The PET acquisition protocol and image interpretation are also discussed.<br /><br />The presentation includes case reviews of patients with suspected cardiac sarcoidosis and their PET findings. It emphasizes the importance of assessing for active inflammation, fibrosis/scar, and RV FDG uptake. It also discusses the use of PET in guiding treatment decisions and monitoring disease activity.<br /><br />Overall, Dr. Chareonthaitawee's presentation provides valuable information on non-perfusion imaging for cardiac sarcoidosis and highlights the key considerations and findings in these studies.
