Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) has been provided for noninvasive assessment of different grade of gliomas. But the diagnostic performance of this new approach was variant among the recent reports. This study included 10 DCE-MRI studies regarding to differentiating high grade gliomas (HGGs) from low grade gliomas (LGGs). The meta-analysis results demonstrated that parameters of DCE-MRI have high diagnostic performanc (Ktrans and Ve) in distinguishing HGGs from LGGs. DCE-MRI can be used as an important tool for the assessment of neovascular permeability and for the pre-operative grading of glioma.
