Value of digital molybdenum target X-ray and diffusion-weighted imaging combined with dynamic contrast-enhanced imaging in the diagnosis of ductal carcinoma in situ and invasive carcinoma of the breast
Objective To explore the value of digital mammography(DM)combined with diffusion-weighted imaging(DWI)and dynamic contrast-enhanced imaging(DCE)in the diagnosis of ductal carcinoma in situ(DCIS)and invasive ductal carcinoma(IDC).Methods The imaging data of 49 patients with breast cancer who received DM,DWI and DCE examination in the People's Hospital of Longhua,Shenzhen,Affiliated to Southern Medical University from January 2021 to December 2022 was retrospectively analyzed.According to the pathological results,it was divided into DCIS group(n=20)and IDC group(n=29).The differences in performance between the two groups on DM,DWI and DCE were compared,and the diagnostic efficacy of various imaging indicators was calculated.Kappa test was used to evaluate the consistency between diagnostic methods.Results The differences in calcification,mass,diffusion coefficient(ADC),signal intensity,internal enhancement,and peripheral enhancement between the DCIS group and the IDC group were statistically significant(P<0.05),DM detected 16 cases of DCIS and 25 IDC cases.DW detected 17 cases of DCIS and 27 IDC cases.DCE detected 18 cases of DCIS and 27 IDC cases.The combination of DM,DWI,and DCE detected 19 cases of DCIS and 28 IDC cases.The total compliance rate of DM examination results was 83.67%;The total compliance rate of DWI examination results was 89.80%the total compliance rate of DCE examination results was 91.84%the overall compliance rate of DM+DWI+DCE combined examination was 95.92%,which was higher than the overall compliance rate of DM,DWI and DCE alone examination.The Kappa consistency test results showed that DM+DWI+DCE had good consistency in the differential diagnosis of DCIS and IDC(P<0.05).Conclusion The combined application of DM,DWI,and DCE has high value in the diagnosis of breast DCIS and IDC,which can improve the differential efficiency of DCIS and IDC,and help guide clinical treatment and prognosis evaluation.
