The DESS sequence has been used to acquire diffusion-weighted images, and this study evaluates DESS images relative to EPI DWI images. Four radiologists were surveyed about the image quality and BI-RADS scores of images containing pathology-proven breast lesions. The DESS sequence acquired sharper diffusion-weighted breast images than EPI (p<0.001). ROC curves were calculated from the BI-RADS scores, and the DESS sequence had a larger AUC (0.74 for DESS, 0.68 for EPI) and a tighter confidence interval. Better image quality facilitates morphological assessment of lesion malignancy.
