Gliomas: Histogram Analysis of Apparent Diffusion Coefficient Maps with Standard- or High-<i>b</i>-Value Diffusion-weighted MR Imaging—Correlation with Tumor Grade

Abstract

Histogram analysis of ADC maps based on entire tumor volume can be a useful tool for grading gliomas. The fifth percentile of the cumulative ADC histogram obtained at a high b value was the most promising parameter for differentiating high- from low-grade gliomas.
