Papillary lesions have a broad spectrum of appearances on magnetic resonance imaging ( MRI ). The purpose of this study was to evaluate whether apparent diffusion coefficient ( ADC ) values of papillary lesions can be used to characterize lesion as benign or malignant. This retrospective study included 29 papillary lesions. Diagnostic values of dynamic contrast‐enhanced MRI (DCE‐MRI), DWI ‐ ADC , and DCE ‐ MRI plus DWI ‐ ADC were separately calculated. The malignant papillary lesions (0.744×10 −3 mm 2 /s) exhibited significantly lower mean ADC values than the benign lesions (1.339×10 −3 mm 2 /s). Addition of DWI to standard DCE ‐ MRI provided 100% sensitivity. We hypothesized that this combination may prevent unnecessary excisional biopsies.
