“…We measured the maximum standardized uptake value (SUVmax) in the myocardium on 215 consecutive FDG-PET/CT at different fasting duration with no dietary modification (12), and also found that SUVmax in the myocardium is significantly reduced only in the group of patients with more than 18-h overnight fasting (Fig. 2).…”

Abnormal uptake of 18 F-fluorodeoxyglucose (FDG) in the heart on positron emission tomography (PET) was recently included in the major criteria of diagnostic guidelines for cardiac sarcoidosis (CS). The high sensitivity but great variability in specificity in the diagnosis probably due to variable preparation methodologies of FDG-PET was reported. There are three main methods which have been reported to minimize physiological FDG uptake in the normal myocardium. A low carbohydrate diet on the day before PET with an overnight fasting more than 18-h achieves almost complete suppression of myocardial FDG uptake. Use of heparin pre-injection or high-fat diet preparation may enhance the suppressive effect. Serum FFA levels before PET imaging might be a biomarker of predicting the physiological FDG uptake in the myocardium.

The myocardium and the cardiovascular system are often involved in patients with sarcoidosis. As therapy should be started as early as possible to avoid complications such as left ventricular dysfunction, a prompt and reliable diagnosis by means of non-invasive tests would be highly warranted. Among other techniques, 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) has emerged as a high sensitive tool to detect sites of inflammation before morphological changes are visible to conventional imaging techniques. We therefore aim at summarizing the most relevant findings in the literature on the use of 18F-fluorodeoxyglucose PET in the diagnostic workup of cardiac sarcoidosis and to underline future perspectives.
