Combined functional (MR perfusion) and metabolic (FDG-PET)
assessment of brain tumors using hybrid MR-PET provides
good accuracy and complimentary information about brain
tumors which could be useful as a diagnostic and
surveillance tool. PWI and tumor blood volume estimation
performs better as compared to FDG uptake assessment in
differentiating low versus high-grade tumors as well as
in differentiating recurrent tumor from
treatment/radiation induced necrosis in previously
treated patients in a concurrent hybrid setting.
