Synopsis

Intravoxel incoherent motion (IVIM) imaging provides quantitative measurement of ADC_slow for cellularity and ADC_fast and f_fastfor vascularity. It is helpful for the differentiation between benign and malignant breast lesions. This study concerned perfusion as well as diffusion parameters of T1 breast carcinoma lesions using IVIM imaging based on the biexponential analysis and then compared these parameters from T₁-weighted, T₂-weighted and contrast-enhanced MR images on the classification of high and low aggressiveness of T1 breast carcinomas.
