Multi-modal MR Functional Imaging Parameters Evaluate the Reactivity of the Reactivity of the Auxiliary Chemotherapy in Patients with Breast Cancer Patients
Objective To evaluate the value of diffusion-weighted imaging(DWI)and dynamic enhanced MR imaging during adjuvant chemotherapy in breast cancer patients before surgery.Methods Between January 2020 and October 2022,43 breast cancer patients treated in hospitals were selected for the study sample,who all underwent dual testing of diffusion-weighted imaging(DWI)and dynamic enhanced MR.At the same time,the functional image parameters of both MR types were also collected,and then the changes of these parameters were analyzed in detail,and finally,their diagnostic accuracy in pathology was evaluated.Results The comparison of LD values showed that there was no obvious difference between the two groups,P＞0.05;however,the ADC,E,and Emax values in the MHR group exceeded the NMHR group,P＜0.05.By using the pathological response after surgery as the"gold standard"to depict the ROC curve graph,the diagnostic accuracy of all indicators of breast cancer was very high.The binary Logistic regression analysis revealed a positive association between LD,ADC,E,Emax values and adjuvant chemotherapy response before surgery in breast cancer patients.This suggests that it is closely linked to the effect of adjuvant chemotherapy in breast cancer patients before surgery.Conclusion For breast cancer patients,the effect of adjuvant chemotherapy before surgery can be accurately evaluated by combining the quantitative indicators of diffusion-weighted imaging(DWI)and dynamic enhanced MR imaging,which will provide important support for the following medical treatment work.
