Abstract ObjectiveTo explore the application value of color Doppler ultrasound (CDUS)and magnetic resonance imaging (MRI)in the diagnosis of breast cancer.MethodsThe clinical data of 130 patients with breast diseases admitted to our hospital from June 2014 to May 2016 were collected.Control pathological examination results,the diagnostic accuracy of breast cancer and mass,Mao Cizheng,calcification of CDUS elastography and 3.0 T MRI were compared.ResultsThe diagnostic accuracy of MRI for benign and malignant breast lesions was 73.3%and 67.4%,respectively.The diagnostic accuracy of CDUS elastography in benign and malignant breast lesions was 74.6%and 75.6%,respectively, with a certain rate of missed diagnosis.CDUS elastic imaging was sensitive to the masses,but it was not sensitive to calcification and Mao Cizheng.MRI had high sensitivity to burr sign and mass,but had low sensitivity to calcification.There were own advantages and disadvantages in the two separate applications.CDUS elastography combined with MRI could further improve the detection rate of breast cancer patients,Mao Cizheng and calcification (χ2=10.736,3.125,22.428,P＜0.05).ConclusionCDUS elastography and MRI alone for the diagnosis of breast cancer have a certain rate of missed diagnosis and misdiagnosis,but after the combination of the two methods,the rate of diagnosis of breast mass,Mao Cizheng and calcification are significantly increased,it can provide reference for early diagnosis of breast cancer.
