Cardiac uptake patterns in routine 18F-FDG PET-CT scans: A pictorial review.

Broad variability of 18F-Fluoro-2-deoxyglucose (FDG) uptake is noted in myocardium while performing FDG PET-CT scans for viability, infection, or oncologic purposes. While most of the uptakes are considered non-specific, presence of underlying cardiac disease is seldom encountered. With this presentation, our intent is to pictorially highlight the variable FDG uptake patterns associated with the normal variations, benign, and malignant disease.
