Forty (27 male and 13 female; mean age=43 yrs) untreated consecutive patients (25 high grades & 15 low grades on histopathology) with a postoperative diagnosis of either high or low grade glioma were imaged using 3D PC-ASL and DCE MRI. On Students independent t-test, all the DCE derived metrics except ve (p=0.29) were found to be significantly higher in high grade as compared to low grade glioma (p<0.001), whereas ASL derived CBF did not show any significant differences (p=0.62). We conclude that DCE-MRI proved to be superior in differentiating high grade from low grade glioma as compared to 3D PC-ASL technique.
