To solely apply DWI to a non-selected group of MRI patients and to compare its diagnostic accuracy to ceMRI in a multi-reader study. 60 consecutive patients with an imaging abnormality were included in this retrospective IRB approved study. Two experienced readers trained in different institutions independently read DWI and CE-MRI examinations and assigned a diagnosis (BIRADS scale 1=no lesion to 5= definite malignancy). Sensitivity, specificity, diagnostic accuracy and inter-reader variability (kappa statistics) were calculated for both readers. DWI for breast cancer diagnosis in breast MRI is feasible with a comparable sensitivity equal to ceMRI.
