DKI model may provide
additional information and improve the characterizing of breast lesions compared
with conventional diffusion parameters. The kurtosis and water molecular
diffusion heterogeneity index derived from DKI and stretched Exponential DWI may be helpful for the preoperative
differentiation of proliferative activity of breast cancer.
