Radiomics assessment of bladder cancer grade using texture features from diffusion-weighted imaging.
To 1) describe textural features from diffusion-weighted images (DWI) and apparent diffusion coefficient (ADC) maps that can distinguish low-grade bladder cancer from high-grade, and 2) propose a radiomics-based strategy for cancer grading using texture features. ⋯ 3 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2017;46:1281-1288.
