Differential Diagnosis between Low-Grade and High-Grade Astrocytoma Using System A Amino Acid Transport PET Imaging with C-11-MeAIB: A Comparison Study with C-11-Methionine PET Imaging

<div>A case of a forty-year-old male who had a diffusely irregular-shaped mass in the left frontal lobe, which was diagnosed as astrocytoma, grade II after surgery (benign group) (case #4). High uptake of MET was in the tumor, while no significant uptake of MeAIB was noted.</div>
