The diagnostic value assessment of MRI and ultrasound imaging in breast intraductal papilloma diagnosis / 中国医学装备

ABSTRACT

Objective:To evaluate the diagnostic value of MRI and ultrasound imagingr in the breast intraductal papilloma.Methods: 29 patients with multiple or isolated breast intraductal papilloma were selected, who were pathologically confirmed. All patients underwent preoperative breast X-ray, ultrasound, dedicated breast MRI plain and dynamic enhanced MRI. According to Breast Imaging Reporting and Data System (BI-RADS), we observed the lesion size, shape, location, margin, polymorphism and its relationship with the catheter by the ultrasound and MRI scan, and analyze enhancement pattern of dynamic contrast-enhanced MRI lesion. Results: In 29 cases of patients with 30 lesions, a total of 28 lesions were detected by MRI, including one patient with bilateral lesions which were positive, and two cases of malignant tumor which were difficult to identify. 25 lesions were detected by ultrasound, in which 4 cases were negative. There were statistical differences in BI-RADS classification of lesions detected by ultrasound and MRI(Z=-2.377,P<0.05). The detection rate of malignant intraductal papilloma lesion by MRI was higher than ultrasound.Conclusion: MRI and ultrasound imaging can be used for diagnosis of intraductal papilloma, but the MRI is superior to ultrasound scanner in lesion detection rate and accuracy, especially in the intraductal papilloma of benign and malignant.
