ADC variables for lymphoma and GBM using three different ROI methods.

ROI, region of interest; ADC, apparent diffusion coefficients;min, minimum; max, maximum; SD, standard deviation; GBM, glioblastoma.ROI1 indicates whole tumor volume; ROI2, most enhancing portion; ROI3, conventional ROI method(any enhancing portion avoiding cyst).*indicates statistical significance (pADC variables for lymphoma and GBM using three different ROI methods.ROI即感兴趣区（region of interest）；ADC为表观扩散系数（apparent diffusion coefficients）；min指最小值（minimum）；max指最大值（maximum）；SD为标准差（standard deviation）；GBM为胶质母细胞瘤（glioblastoma）。其中ROI1代表全肿瘤体积；ROI2为强化最显著的区域；ROI3为常规感兴趣区方法（避开囊变区的所有强化区域）。*表示存在统计学显著性，该显著性对应采用三种不同感兴趣区方法得到的淋巴瘤与胶质母细胞瘤的ADC变量。
