Fig. 1From: Grading of meningioma tumors based on analyzing tumor volumetric histograms obtained from conventional MRI and apparent diffusion coefficient imagesThe examples of MRI images and ADC histograms from different grades of meningioma tumors in one slice of brain. A An ADC image with grade I (contoured with red line). B An ADC image with grade II (contoured with purple line). C An ADC image with grade III (contoured with blue line). D A volumetric intensity histogram of grade I. E A volumetric intensity histogram of grade II. F A volumetric intensity histogram of grade IIIBack to article page
