Modeling the diffusion‐weighted imaging signal for breast lesions in the b = 200 to 3000 s/mm ² range: quality of fit and classification accuracy for different representations

Purpose To evaluate different non‐Gaussian representations for the diffusion‐weighted imaging (DWI) signal in the b‐value range 200 to 3000 s/mm 2 in benign and malignant breast lesions. Methods Forty‐three patients diagnosed with benign (n = 18) or malignant (n = 25) tumors of the breast underwent DWI (b‐values 200, 600, 1200, 1800, 2400, and 3000 s/mm 2 ). Six different representations were fit to the average signal from regions of interest...
