Apparent Diffusion Coefficient. The diffusion coefficients we measure with MRI represent averages of the entire voxel and of each direction of diffusion (see discussion about anisotropy and DTI later). WebAbstract. Background The diagnostic accuracy of diffusion-weighted imaging (DWI) to detect prostate cancer is well-established. DWI provides visual as well as quantitative means of detecting tumor, the apparent diffusion coefficient (ADC). Recently higher b-values have been used to improve DWI's diagnostic performance. fish neuromast
