Objectives  To investigate the application of apparent diffusion coefficient (ADC) histogram analysis in differentiating between benign and malignant breast lesions detected as non-mass enhancement on MRI.    Materials and Methods  A retrospective study was conducted for 25 malignant and 26 benign breast lesions showing non-mass enhancement on breast MRI. An experienced radiologist without prior knowledge of the pathological results drew a region of interest (ROI) outlining the periphery of each lesion on the ADC map. A histogram was then made for each lesion. Following a univariate analysis of 18 summary statistics values, we conducted statistical discrimination after hierarchical clustering using Ward’s method. A comparison between the malignant and the benign groups was made using multiple logistic regression analysis and the Mann-Whitney  U  test. A  P  -value of less than 0.05 was considered statistically significant.    Results  Univariate analysis for the 18 summary statistics values showed the malignant group had greater entropy ( P  &lt; 0.001) and lower uniformity ( P  &lt; 0.001). While there was no significant difference in mean and skewness values, the malignant group tended to show a lower mean ( P  = 0.090) and a higher skewness ( P  = 0.065). Hierarchical clustering of the 18 summary statistics values identified four values (10th percentile, entropy, skewness, and uniformity) of which the 10th percentile values were significantly lower for the malignant group ( P  = 0.035).    Conclusions  Whole-lesion ADC histogram analysis may be useful for differentiating malignant from benign lesions which show non-mass enhancement on breast MRI.
