This study aimed to demonstrate that the Scale-PWI sequence with absolute quantification for cerebral perfusion in the solid region of the tumors was a meaningful diagnostic factor in grade-II and grade-III gliomas. Total 8 glioma patients (4 grade II , 4 grade III) were subjected Scale-PWI scanning. ROC analysis confirmed that has great accuracy in grading World Health Organization (WHO) II and III gliomas.
