[Abstract] Objective: This study was designed to investigate the role of texture analysis and dynamic contrast-enhanced MR based on different regions of interest (ROI) in determining glioma grade.Materials and Methods: Forty cases of high-grade glioma (grade Ⅲ and Ⅳ WHO) and low-grade glioma (grade Ⅰ and Ⅱ WHO) confirmed by pathology were collected. All patients underwent routine MRI and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). ROI is determined by the following two areas: (1) the whole tumor area; (2) the solid part of the tumor. Texture features between high-grade glioma (HGG) and low-grade glioma (LGG) were compared by nonparametric Wilcoxon rank sum test.Results: For the whole tumor ROI, the value of inhomogeneity between HGG and LGG was significantly different (Z=50.37, P=0.01 <0.05). For the real part of ROI, the inhomogeneity showed that the difference between HGG and LGG was not statistically significant (Z=34.65, P=0.06>0.05). The whole tumor inhomogeneity parameter performed with better diagnostic accuracy.Conclusions: Texture analysis of DCE-MRI based on different ROI can provide reliable value for evaluating glioma grade.
