Objective: To evaluate the diagnostic value of combining 3D artery spin labeling and intravoxel incoherent motion in grading of cerebral gliomas. Materials and Methods: A total of 32 patients with histopathology proved gliomas(13 low grade, 19 high grade) were included in this study. 3D ASL and multi-b IVIM images were retrospectively analyzed. The ASL and IVIM data were processed on workstation to get the CBF and D, D*, f values. The results were compared among high grade and low grade groups and P<0. 05 w...
