Intravoxel incoherent motion (IVIM) imaging provides quantitative measurement of ADCslow for cellularity and ADCfast and ffast for vascularity. The parameters derived from IVIM can distinguish lesions of different aggressive pathological subtypes of Stage T1 breast carcinomas[1]. This study concerned clinical features, perfusion as well as diffusion parameters using IVIM imaging and then compared these parameters from conventional MR images on the classification of Stage T1 HER2-positive and HER2-negative breast carcinoma lesions .
