Abstract

Abstract: This paper is to investigate the diagnostic value of superb microvascular imaging (SMI) and contrast enhanced ultrasound (CEUS) in microblood flow and ultramicro-blood vessels in breast cancer. 106 cases (106 masses) of breast cancer confirmed by surgery and pathology in our hospital from June 2017 to March 2019 were selected as the study subjects.All patients underwent color Doppler flow imaging (CDFI), CEUS and SMI before operation. The diagnostic accuracy of SMI and CEUS in breast cancer and the display of blood flow signals and perforating vessels in the lesions were compared. The results show that among 106 cases of breast cancer (106 masses), the diagnostic accuracy of SMI and CEUS for breast cancer was 79.25% and 83.96%, respectively, with no significant difference (P>0.05). The diagnostic accuracy of SMI combined with CEUS in breast cancer was 96.23%, which was significantly higher than that of single SMI or CEUS (P<0.05). On the display of blood flow signals, 64 blood flow signals were not rich and 42 blood flow signals were rich detected by SMI. CEUS showed low enhancement in 64 cases, equal enhancement and high enhancement in 42 cases respectively. SMI and CEUS had good consistency in evaluating microvascular and blood flow in breast cancer lesions (P<0.05). On the display of perforating vessels, 44 cases were detected by SMI and 34 cases by CDFI. SMI could clearly detect 10 perforating vessels which could not be detected by CDFI. Research shows:SMI and CEUS have good consistency in the diagnosis of microvascular and blood supply in breast cancer lesions, and have high diagnostic value for breast cancer. The combined examination of SMI and CEUS is helpful to improve the diagnostic accuracy of breast cancer.
