Objective To explore the value of MRI in the differential diagnosis of benign and malignant non mass like enhancement(NME)lesions.Methods A retrospective analysis was conducted on the imaging and clinical data of 107 female patients(39 cases of benign lesions and 68 cases of malignant lesions)who showed NME on breast MRI images of our hospital and obtained pathological results through puncture or surgery.The distribution types,enhancement methods,ADC values,and time signal intensity curves(TIC)of NME were analyzed and compared between the benign and malignant groups.Multivariate binary Logistic regression analysis was conducted on meaningful influencing factors to screen out risk factors for predicting malignant diseases.Results The results of multivariate binary Logistic regression analysis showed that segment distribution,cluster ring enhancement,type Ⅲ TIC curve,and ADC values were identified as significant factors for predicting malignant breast NME lesions(OR=3.889,95％CI:0.629-24.049;OR=15.367,95％CI:2.602-90.769;OR=7.262,95％CI:1.315-40.099;OR=0.997,95％CI:0.995-0.998,respectively;P＜0.05).Conclu-sion MRI enhanced features and ADC values can effectively improve the differential diagnosis of benign and malignant breast NME lesions.
