Perfusion parameters, derived from T1-weighted dynamic contrast enhanced imaging and arterial spin labeling, of tumor and normal brain tissue in patients with GBM were tracked for 6 months after receiving anti-angiogenic therapy. Kps, fBV, and CBF levels in the tumor region were seen to decrease significantly 6 months after treatment with noticeable changes within individual patients by 2 months after treatment. The results from this study suggest that perfusion imaging is a useful tool for assessing the effects of this therapy and possibly assisting early prediction of progression for patients with GBM.
