¹⁸F-FDG Myocardial Uptake Related to Continuous Venovenous Hemodialysis: The Importance of Eliminating All Things Sweet

When ¹⁸F-FDG PET/CT is used to diagnose cardiovascular inflammation or infection, it is important to differentiate between pathologic and physiologic ¹⁸F-FDG myocardial uptake. Several methods to suppress physiologic ¹⁸F-FDG myocardial uptake have been reported, all based on the principle of promoting free fatty acid metabolism over glucose metabolism. However, despite rigorous implementation of these protocols, there is variation in successful myocardial glucose suppression. Sometimes this variation can be explained by specific patient conditions or treatment regimes. Here, we describe a patient on continuous venovenous hemodialysis with ¹⁸F-FDG myocardial uptake despite adequate preparation.
