Objective Analysis of the effectiveness of magnetic resonance imaging combined with ultrasound elastography in the differential diagnosis of benign and malignant breast tumors.Methods Retrospective analysis of data was collected from 98 breast tumor patients admitted to Liaocheng Infectious Disease Hospital from August 2022 to August 2023.All patients underwent preoperative ultrasound elastography and magnetic resonance imaging examinations.Using histopathological results as the gold standard,to analyze the diagnostic efficacy of ultrasound elastography,magnetic resonance imaging single and combined examinations for breast tumors,Kappa coefficient was used to evaluate the consistency of different examination methods and pathological diagnosis.Results(1)The histopathological results showed that among 98 breast tumor patients,55 were malignant(malignant group)and 43 were benign(benign group).In ultrasound elastography examination,the proportion of patients in the benign group with 1～3 points was higher than that in the malignant group,and the proportion of patients in the 4-5 points was lower than that in the malignant group(P<0.05).(2)In magnetic resonance imaging examination,the number of lesions with flaky and round shape in benign group was higher than that in malignant group,and the number of edge burrs and irregular lesions was lower in malignant group(P<0.05).(3)The sensitivity,accuracy,positive predictive value and negative predictive value of the combined examination of ultrasound elastography and magnetic resonance imaging were higher than those of a single examination of ultrasound elastography(P<0.05).(4)The consistency between ultrasound elastography diagnosis and pathological diagnosis is acceptable(Kappa value=0.508),while magnetic resonance imaging has good consistency with pathological diagnosis(Kappa value=0.855).The consistency between combined examination and pathological diagnosis is excellent(Kappa value=0.896).Conclusion The differential diagnosis of benign and malignant breast tumors by the combined examination of MRI and ultrasound elastography is more effective.
