Abstract Objective: To analyze the application value of 3.0T MR dynamic enhancement curve combined with ADC in differential diagnosis of benign and malignant breast lesions. Methods: The patients with breast lesions from January 2017 to March 2019 in our hospital were divided into benign lesion group and malignant lesion group according to the pathological diagnosis. The subjects were examined with 3.0T MR and the ROC curve analysis was dynamically enhanced. Curve combined with ADC was for the differential diagnosis of benign and malignant breast lesions. Results: There were significant differences in the dynamic enhancement curves between the benign lesion group and the malignant lesion group, and the difference was statistically significant(P<0.05). The ADC value of the benign lesion group was significantly lower than that of the malignant lesion group, and the difference was statistically significant(P<0.05). The results of dynamic enhancement curve analysis were 73 cases of benign breast lesions. The results of ADC analysis were 72 cases of benign breast lesions. The combined application analysis showed 70 cases of benign breast lesions. The combination of dynamic enhancement curve and ADC value was used to differentially diagnose breast. The sensitivity, specificity and AUC of benign and malignant were significantly higher than those of each index, and the difference was statistically significant(P<0.05). Conclusion: The sensitivity and specificity of the differential diagnosis of benign and malignant breast lesions using 3.0T MR dynamic enhancement curve combined with ADC were significantly higher than those of the enhancement curve or ADC alone.
