Abstract

Abstract: This study explored the value of magnetic resonance diffusion-weighted imaging (MR-DWI) in assessing axillary lymph node metastasis in breast cancer patients. 68 cases of breast cancer patients were selected as the observation group, and 60 cases of benign breast lesions were selected as the control group, the differences of MR-DWI imaging between the two groups were compared. The proportion of diffuse high signal and mixed high signal in the observation group was significantly higher than that in the control group (P<0.05). The ADC value of the observation group w was significantly lower than that of the control group (P<0.05). The ADC value of stage Ⅲ lesions in the observation group was significantly lower than that of stage Ⅰ-Ⅱ lesions (P<0.05). The ADC value of axillary lymph node metastasis in the observation group was significantly lower than that without lymph node metastasis (P<0.05). There was no significant difference in ADC between diffuse high signal and other signal tissues (P>0.05). The area under ROC curve of ADC value in the diagnosis of axillary lymph node metastasis was 0.752, P<0.05. MR-DWI has great value in the diagnosis of breast cancer and axillary lymph node metastasis, which is worthy of clinical application.
