Diagnostic Value of Multi Parameter Magnetic Resonance Imaging in Triple Negative Breast Cancer
Objective To invstigate the diagnostic value of MRI multi parameters and their combination in TNBC.Methods A retrospective analysis was made on 160 cases of breast cancer confirmed by pathology,including 45 cases of TNBC and 115 cases of non TNBC.All patients underwent MRI examination and analysis.Results In the TNBC group,the tumor shape was mostly circular,the edge was smooth,and the enhancement was mostly circular,the differences were statistically significant(P＜0.05);the D value,f value,and MD value of the TNBC group were higher than those of the non TNBC group,while the MK value was lower than that of the non TNBC group,with statistical differences(P＜0.05);the AUC of conventional MRI model was 0.816,which was larger than that of single features of shape,edge and enhancement mode(P＜0.001);the AUC of IVIM+DKI model was 0.870,which was larger than that of single model,and the difference was statistically significant(P＜0.001);in addition,the diagnostic efficiency of IVIM+DKI model was higher than that of single parameters D,f,MD and MK(P＜0.001);the AUC of the combined model was 0.971,and the diagnostic efficiency was higher than that of the single model(P＜0.001).Conclusion The multi-parameter MRI model can be used for the diagnosis of TNBC,and the combined model has better diagnostic efficacy than the single model,which is conducive to the personalized diagnosis and treatment and prognosis assessment of TNBC patients.
