Hybrid Methionine PET/MR imaging in a 45-year-old patient with a non-enhancing glioma on the left frontal gyrus. The fused PET–FLAIR-T2w image (a) shows avid radiolabeled amino-acid tracer uptake on the posterior part of the tumour in the precentral gyrus (arrow), whereas the proton MR spectroscopy Choline map (b) demonstrates a second focus of increased cell proliferation on the anterior part of the lesion (dashed arrow). The perfusion MR (intravascular blood volume map) (c) shows in concordance with the PET a “hot-spot” with increased vascularity on the precentral gyrus (arrow). Due to the eloquent character of the metabolically active lesion site (motor strip), simultaneous diffusion tensor imaging (DTI) was acquired to determine the location of the pyramidal motor track and help to guide the neurosurgical biopsy, thus avoiding motor function impairment
