ABSTRACT

Objective To compare the clinical diagnostic value of ultrasound and magnetic resonance imaging (MRI) in breast cancer.Methods Ultrasound and MRI were performed in patients with breast disease.The postoperative pathological examination results were seemed as diagnostic criteria.The diagnostic accuracy was analyzed in two kinds of imaging examination.Results The diagnostic accuracy of MRI in breast cancer(86.9％) was significantly higher than the accuracy of ultrasonic diagnosis(39.3％),the sensitivity and specificity of MRI were significantly higher than those in ultrasonic diagnosis,the rate of missed diagnosis and misdiagnosis rate of MRI were lower than those of ultrasonic diagnosis,the differences were statistically significant (x2 =6.583,12.573,4.892,23.175,8.649,all P ＜ 0.05).Conclusion Ultrasound and MRI have high ability in diagnosis of breast cancer.MRI diagnostic efficacy has more advantages,but the ultrasound is convenient to operate and repeate inspection,can be used in screening.
