Brain stimulations, such as motor stimulations, result in hypermetabolism in the area of the brain that is impacted by that stimulation and on PET FDG images this area will light up. If the patient exercises his or her left arm 30 min before the procedure which area of the brain will show increased radiotracer uptake during the PET FDG scan?

PET
The time from F-18 fluorodeoxyglucose (FDG) administration to the time of data acquisition has been shown to have a marked effect on FDG uptake. An increased interval between the injection and imaging uptake time will DECREASE radiotracer concentration in:
