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. WebA simple example demonstrates that the B_matrix is underspecified to store the polarity of the B_vector. Consider the B_vector [1, 0,0] and its polar opposite [-1,0,0]: both create the B_matrix [1,0,0; 0, 0,0; 0,0,0].
