[Abstract]:Objective: To evaluate the value of super microvascular imaging (SMI) in the identification of axillary lymph node metastases in breast cancer, and to evaluate the advantages and value of SMI in determining the form and distribution of the blood flow in the axillary lymph nodes, and to provide a new way of thinking for the identification of axillary lymph nodes. 67 axillary lymph nodes of breast cancer patients were selected in accordance with the inclusion criteria. The Toshiba Aplio 500 color Doppler ultrasound diagnostic apparatus, the 14L5 linear array probe, the frequency 14.0MHz, and the built-in SMI imaging software were used. First, the conventional two-dimensional gray scale ultrasound examination was performed on the basis of the two-dimensional ultrasound examination, and the color Doppler flow imaging (CDFI) was used. The blood vessels in the lymph nodes were scintid with the standard procedure of SMI, and the maximum distribution density, the most branches and the most abundant tangent surfaces in the lymph nodes were selected. The distribution of blood flow was observed and the dynamic images were recorded for analysis. Finally, the dynamic images were stored for analysis with all surfaces, and the dynamic images were stored for analysis. The results of the examination were qualitative diagnostic gold standard. The sensitivity, specificity, positive predictive rate, negative predictive rate and accuracy of two-dimensional gray scale ultrasound combined with CDFI, two-dimensional gray scale ultrasound combined with SMI and CEUS in the differential diagnosis of lymph node benign and malignant, and the criteria for determining the microvascular distribution in the lymph nodes by CEUS were used for the analysis of CDFI and SMI. The pattern of microvascular distribution in the lymph nodes was consistent with CEUS. Finally, a multi factor logistics regression analysis was performed on two-dimensional ultrasound signs and SMI assessment of the distribution of the axillary lymph nodes and the spiral vessels. Results: (1) the pathological examination was the gold standard, and the two dimensional gray scale combined with CDFI in the diagnosis of the benign and malignant axillary lymph nodes of the breast cancer patients Accuracy of 73.1%. two-dimensional gray scale combined with SMI in the diagnosis of benign and malignant axillary lymph nodes in breast cancer patients the accuracy of 86.6%. two-dimensional gray scale combined with CEUS for the diagnosis of benign and malignant axillary lymph nodes in breast cancer patients 89.6%. two dimensional combination of CEUS and CDFI accuracy has significant statistical significance (x 2=5.950, P0.01); two-dimensional joint SMI and CDFI quasi accurate The difference in accuracy was statistically significant (x 2=3.757, P0.05); there was no statistically significant difference in the accuracy of the two dimensional combination of CEUS and SMI (x 2=0.284, P0.05). (2) the microvascular distribution in the benign lymph nodes was dominated by the II type lymphatic type, and the microvascular distribution in the metastatic lymph node was dominated by the IV type mixed type. The consistency of blood flow distribution in CDFI and CEUS is high (Kappa=0.7070.75). The consistency of blood flow distribution in SMI and CEUS is very high (Kappa=0.8580.75). Statistical analysis shows that CDFI, SMI and CEUS have very high consistency in judging the blood flow distribution of the II lymphohilus type in the lymph nodes, followed by IV type mixing. (3) the detection rate of specific spiral vessels in metastatic lymph nodes was found to be 51.6% by the SMI model. The OR value of single factor logistics regression analysis was 18.133, the 95% confidence interval of OR value was 3.696~88.972, and P0.05. (4) multiple factor logistics regression analysis showed that the OR value of four kinds of blood flow distribution in axillary lymph nodes under SMI was 24.332, The OR value of spiral vessels in the axillary lymph nodes was 23.044, and the AUC 0.815,95% confidence interval of the regression equation prediction curve was 0.709~0.921. conclusion: (1) the difference of CDFI accuracy was statistically significant compared with the SMI and CEUS in the evaluation of the axillary lymph node properties, and there was no statistical difference between SMI and CEUS, suggesting that SMI and CEUS were in the evaluation of axillary lymph nodes. (2) the consistency of CDFI and SMI in the determination of blood flow in the lymph nodes was higher, but the Kappa0.75 of SMI reached a higher consistency, suggesting that the assessment of the type of blood flow distribution in the axillary lymph nodes was more reliable. (3) SMI could clearly show the specific spiral vessels in the metastatic lymph nodes and the spiral vessels within the SMI. The OR value of single factor logistics regression analysis was 18.133, suggesting that SMI imaging found that spiral vessels may be an independent risk factor for evaluating the properties of lymph nodes. (4) the multiple factor logistics regression analysis of the distribution types of axillary lymph nodes and the spiral vessels in the axillary lymph nodes by SMI technique suggests the detection of both of the two. The important predictors of axillary lymph node properties are better predictors.
