Unilateral Diffusely Increased Muscle Uptake of F-18 FDG in a Patient With Hemiparesis Due to Stroke

No idea what this is trying to say, unless they're trying to say they found an objective way to determine spasticity.

Abstract

Although normal muscles accumulate less F-18 fluorodeoxyglucose (FDG) under normoglycemic conditions, FDG muscle uptake is frequently encountered on PET scans. However, diffusely elevated unilateral muscle uptake is not frequently seen. In this report, we demonstrate a case of unilateral muscle uptake in a patient with a remote history of stroke, possibly explained by increased spasticity, a shift toward fast twitch (type II) muscle fibers, and inflammatory changes that are all seen post–upper motor neuron injury. Thus, FDG PET may serve as a functional biomarker of the extent of upper motor neuron injury after stroke.
