Objective To perform quantitative analysis on the efficacy of using relative cerebral blood flow (rCBF) in arterial spin labeling (ASL), relative cerebral blood volume (rCBV) in dynamic magnetic sensitivity contrast-enhanced magnetic resonance imaging(DSC-MRI), and mean kurtosis (MK) in diffusion kurtosis imaging (DKI) to grade cerebral gliomas. Methods Literature regarding ASL, DSC-MRI, or DKI in cerebral glioma grading in both English and Chinese were searched from PubMed, Embase, Web of

A Meta-Analysis was performed to evaluate the efficacy of ASL, DSC-MRI, and DKI in the grading of cerebral glioma. Result A total of 54 articles (11 in Chinese and 43 in English) were included. Three quantitative parameters in the grading of cerebral glioma, rCBF in ASL, rCBV in DSC-MRI,and MK in DKI had an overall sensitivity of 0.88[95%CI(0.83,0.92)], 92[95%CI(0.83,0.96)],0.88[95%CI(0.82,0.92)], and an overall specificity of 0.91[95%CI(0.84,0.94)],0.81[95%CI(0.73,0.88)], 0.86[95%CI(0.78,0.91)] respectively. The overall area under the ROC curve were 0.95[95%CI(0.93,0.97)], 0.91[95%CI(0.89,0.94)], 0.93[95%CI(0.91,0.95)] respectively. Conclusion Quantitative parameters rCBF, rCBV and MK have high diagnostic efficacy for preoperative grading of cerebral gliomas.
