The purpose of this study is to evaluate the capability of Volume Transfer Coefficient (Ktrans) and Interstitial Space Volume Fraction (ve) derived from Reference Tissue (RR) model to differentiate intraaxial brain masses such as low-grade glioma, high-grade glioma, cerebral metastases and meningiomas. The results demonstrated that Ktrans and ve derived from RR model are promising noninvasive imaging modality that could be used for distinguishing intraaxial brain masses.
