This study compared the diagnostic performance of the ADC derived from the diffusion-weighted readout-segmented EPI DWI accelerated with SMS technique (SMS rs-EPI DWI) with that derived from the conventional rs-EPI DWI on breast lesions using whole-tumor histogram analysis. Our results showed that the SMS technique can increase the spatial resolution of the rs-EPI DWI sequence without prolonging the scan time. It can also improve the diagnostic performance of the derived ADC map based on whole-tumor histogram analysis in distinguishing benign and malignant breast lesions.
