Value of ultrasound, magnetic resonance imaging and molybdenum target in differential diagnose of benign and malignant breast masses

Abstract

Objective To investigate the value of ultrasound, magnetic resonance imaging (MRI) and molybdenum target in differential diagnose between benign and malignant breast masses. Methods One hundred patients with breast masses hospitalized in Staff General Hospital of Minxi Mining Group from June 2014 to June 2019 were selected as research objects. And they all underwent pathological examination. Ultrasound, MRI and molybdenum target were performed on the patients prior to operation or 15 days before puncture biopsy. The sensitivity and specificity of the three single detection methods and combined detection in differential diagnose between benign and malignant breast masses were compared, with the pathological results as standards. Results The results of puncture or surgical biopsy in 100 cases of breast masses showed 28 cases (28.00%) of malignant breast masses, and 72 cases (72.00%) of benign breast masses. Among the 100 patients, ultrasound confirmed 83 cases correctly, Kappa=0.608; MRI determined 87 cases correctly, Kappa=0.694; molybdenum target correctly confirmed 78 cases, Kappa=0.488; while a total of 99 cases were diagnosed correctly by combined detection, and the Kappa value was 0.976. The sensitivity, specificity, accuracy and predictive value of combined detection in differentiating benign and malignant breast masses were significantly higher than those of three single detection methods (P<0.05). Conclusions The combined detection of ultrasound, MRI and molybdenum target can effectively improve the accuracy of differential diagnose of benign and malignant breast masses, and provide imaging information for the diagnosis and treatment.
