FIG 1. Relationship of the maximum rCBV of the low- and high-grade gliomas between the GE- (2000/46/1 [TR/TE/excitation]) and the SE-EPI (2000/97/1) techniques. For high-grade gliomas, the maximum rCBV ratios obtained with GE-EPI are significantly higher than those acquired with SE-EPI, whereas there is no significant difference for low-grade gliomas
