Diffusion-weighted imaging (DWI) is increasingly used in MR mammography for assessing malignancy of breast lesions. In particular, quantitative analysis of DWI data acquired with several b-values is gaining importance. Common data evaluation approaches include intravoxel incoherence motion (IVIM) and kurtosis imaging. The aim of this work was to evaluate the performance of kurtosis and IVIM based parameters in comparison to an approach combining several conventional diffusion coefficients measured with different b-values. The dataset comprised 198 examinations of patients with suspicious mammography findings. The simple approach using several ADCs showed a similar performance as the combination of kurtosis and IVIM.
