To evaluate the diagnostic value and imaging features of mammography and contrast-enhanced ultrasonography in breast ductal carcinoma in situ, 60 patients with 62 lesions were selected from 80 patients with ductal carcinoma in situ who were surgically treated and pathologically diagnosed in Huzhou Central Hospital from June 2017 to June 2019. All patients were examined by contrast-enhanced ultrasonography and mammography within 2 w before the operation. The imaging features, diagnostic accuracy, sensitivity, specificity, positive predictive value and negative predictive value of the two methods were analysed. Compared to mammography, sensitivity, specificity, accuracy, positive predictive value and negative predictive value of the contrast-enhanced ultrasound in the diagnosis of benign and malignant breast ductal lesions was significantly better. In terms of imaging features, the contrast-enhanced ultrasound was significantly better than mammography in detecting the boundary and edge of lesions and calcification of lesions, but there was no significant difference between the two methods in the detection of size of the lesions. Contrast-enhanced ultrasound could provide a rapid, reliable, and accurate diagnostic basis for the diagnosis of ductal carcinoma in situ and it is of great significance for the diagnosis and treatment of ductal carcinoma in situ in the clinic. Mammography and contrast-enhanced ultrasound can be combined to improve the accuracy and sensitivity of early diagnosis and screening of ductal carcinoma in situ, which is worthy of clinical application.
