Abstract:
Objective:To analyze the significance of ultrasound super microvascular imaging (SMI) combined with strain ratio (SR) in the differential diagnosis of benign and malignant breast masses.Methods:A total of 110 patients with breast masses (110 lesions) admitted to Jiande Branch of the Second Affiliated Hospital of Zhejiang University from October 2022 to November 2024 were retrospectively selected, including 65 benign masses (benign group) and 45 malignant masses (malignant group). Both groups received SMI and strain elastography (SE) examination. The clinical and ultrasonic parameters SMI blood flow signal grade, vascular index (VI), global SR (ESR), local SR (LSR) and other indicators of the two groups were compared, and the independent risk of breast tumor malignancy was screened by Logistic regression. Receiver operating characteristic (ROC) curve was used to analyze the value of SMI blood flow signal grading, VI and ESR combined detection in the differential diagnosis of breast tumor malignancy.Results:The proportion of irregular shape, unclear boundary, microcalcification, convergence sign and angulation sign in the malignant group were higher than those in the benign group: 80.00%(36/45) vs. 55.38%(36/65), 57.78%(26/45) vs. 33.85%(22/65), 44.44%(20/45) vs. 13.85%(9/65), 55.56%(25/45) vs. 9.23%(6/65), 60.00%(27/45) vs. 15.38%(10/65), there were statistical differences ( P<0.05). The SMI blood flow signal grade in the malignant group was higher than that in the benign group, the VI, ESR and LSR in the malignant group were higher than those in the benign group: (6.53 ± 0.68)% vs. (3.14 ± 0.36)%, 4.62 ± 0.48 vs. 2.53 ± 0.27, 31.45 ± 3.29 vs. 20.16 ± 2.35, there were statistical differences ( P<0.05). Logistic regression analysis showed that irregular shape, unclear boundary, microcalcification, SMI blood flow signal grade, VI and ESR were independent risk factors for malignant breast mass ( P<0.05). ROC curve analysis results showed that the sensitivity, specificity and accuracy of SMI blood flow signal classification, VI and ESR combined in predicting breast tumor malignancy were 84.26%, 83.17% and 87.65%, respectively, and the area under the curve was 0.896, which were higher than the results predicted by each index alone. Conclusions:There are certain characteristic changes of SMI in benign and malignant breast masses. SMI combined with SR has good value in differential diagnosis of benign and malignant breast masses.
