Abstract Objective: To explore the diagnosis value of contrast-enhanced ultrasound(CEUS) and superb micro vascular imaging(SMI) for detecting micro-blood flow and super micro-vessels in breast cancer. Methods: The imaging data of 31 cases with breast cancer proved by operation and pathology were analyzed retrospectively, which were examined by SMI and CEUS before operation, comparing the diagnosis accuracy and detecting the blood flow and perforator vessels. Results: Of all 31 cases, the diagnosis accuracy of SMI, CEUS and combined SMI with CEUS was 80.6%, 87.1% and 93.5% respectively, and compared with single SMI or CEUS, the difference was statistically significant(P＜0.05). For displaying the blood flow signals, SMI showed 12 rich blood flow and 19 poor blood flow. Hyper-enhancement and iso-enhancement were seen in 12 cases and hypo-enhancement in 19 cases, revealing that CEUS results are consistent with SMI. For displaying perforator vessels, SMI detected three perforator vessels which couldn’t be detected with color Doppler ultrasound. Conclusion: SMI and CEUS have important clinical values in the diagnosis of breast cancer, the combination of SMI and CEUS can improve the diagnosis accuracy.
