Prognostic Value of High Frequency Ultrasound Combined with Diffusion-weighted Magnetic Resonance Imaging in Breast Cancer
Objective To investigate the prognostic value of high frequency ultrasound combined with diffusion-weighted magnetic resonance imaging in breast cancer.Methods A total of 95 patients with breast cancer admitted to our hospital from July 2020 to December 2022 were selected as the study objects.All of them underwent radical surgery,Patients underwent preoperative high-frequency ultrasound and magnetic resonance diffusion weighted imaging examination.After 2 years of follow-up,the patients were divided into good prognosis group(70 cases)and poor prognosis group(25 cases).The apparent dispersion coefficient(ADC),peak systolic velocity(PSV),resistance index(RI)and other parameters were compared between groups.Univariate and multivariate Logistic regression were used to analyze the predictive risk value of high frequency ultrasound and magnetic resonance diffusion-weighted imaging for breast cancer prognosis,and receiver operating characteristic(ROC)curves were plotted to evaluate their predictive value for breast cancer prognosis.Results Compared with the good prognosis group,ADC in the poor prognosis group was decreased,PSV and RI were increased(P＜0.05).Multivariate Logistic regression analysis showed that ADC,PSV and RI were the influential factors in predicting the prognosis of breast cancer(P＜0.05).ROC curve showed that the combined detection of ADC,PSV and RI had high predictive value for poor prognosis of breast cancer.Conclusion The combination of high frequency ultrasound and MRI with diffusion-weighted imaging can predict the prognosis of breast cancer.
