label_lc: perisylvian fdg hypermetabolism
description: "18F-fluorodeoxyglucose (FDG) positron emission tomography and computed tomography (FDG-PET/CT) evaluates the glucose metabolism of the brain. FDG uptake is interpreted to represent glycolysis. This term therefore represents an abnormally increased FDG uptake (increased glucose metabolism) in the region of the brain that surrounds the Sylvian fissure."
