Excellent suppression of physiological myocardial FDG activity in patients with cardiac sarcoidosis.

Introduction: Suppression of physiological myocardial FDG activity is vital in patients undergoing PET/CT for assessment of known or suspected cardiac sarcoidosis. This study aims to evaluate the efficacy of physiological myocardial FDG suppression following a protocol change to a 24-h high fat very low carbohydrate (HFVLC) diet and prolonged fast.

Methods: A retrospective review of patients undergoing FDG PET/CT for the evaluation of cardiac sarcoidosis was performed.
