Evaluation of Diagnostic Value of Ultrasound and Magnetic Resonance Imaging for Malignant and Benign Breast Lesions

摘要

Objectives:To investigate diagnostic value of ultrasound and magnetic resonance imaging(MRI)for malignant and benign breast lesions.Methods:Retrospective analysis of treatment data of 48 patients diagnosed with malignant and benign breast lesions in our hospital,collected from December 2017 to November 2018.A total number of 56 breast masses were examined by both ultrasound and MRI,and were compared with postoperative pathological biopsy results.Results:Postoperative pathological biopsy results showed that there were 26 and 30 malignant and benign lesions respectively.Comparison of MRI curve type of malignant and benign lesions showed statistical significance(P<0.05).By comparison with pathological biopsy results,specificity and sensitivity of ultrasound diagnosis were 83.33%(25/30)and 84.61%(22/26)respectively;specificity and sensitivity of MRI diagnosis were 96.66%(29/30)and 92.30%(24/26)respectively.Conclusions:Ultrasonographic examination of malignant and benign breast lesions is straight-forward,simple and inexpensive.Accuracy,specificity and sensitivity of MRI are significantly higher than ultrasound in examining malignant and benign breast lesions,this can reduce misdiagnosis.
