Intravoxel incoherent motion (IVIM) imaging provides quantitative measurement of ADCslow for cellularity and ADC_fast 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 .
