Multiple b-value diffusion weighted imaging (DWI) provides quantitative measurement of ADCslow for cellularity and ADCfast and ffast for vascularity. It is helpful for the differentiation between benign and malignant breast lesions. This study concerned perfusion as well as diffusion information in normal breast tissues and breast lesions from intravoxel incoherent motion (IVIM) imaging based on the biexponential analysis of multiple b-value DWI and then compared these parameters to ADC obtained with monoexponential analysis on the diagnosis of different grades of ductal carcinoma in situ (DCIS).
