Figure 2From: Long fasting is effective in inhibiting physiological myocardial 18F-FDG uptake and for evaluating active lesions of cardiac sarcoidosisVisual evaluation of myocardial 18F-FDG uptake using a four-point scale. Myocardial 18F-FDG uptake was lower than hepatic uptake (A, grade 1), similar to hepatic uptake (B, grade 2), somewhat higher than hepatic uptake (C, grade 3), and noticeably higher than hepatic uptake (D, grade 4). Grade 1 can be recognized as a complete inhibition of physiological uptake.Back to article page
