Abstract: Objective To explore the value of contrast-enhanced ultrasound ( CEUS) in evaluating the effect of liver cancer ablation. Methods A total of 46 patients with liver cancer (60 lesions) were treated with microwave ablation between May 2008 and October 2016.After 1 month, color Doppler flow imaging ( CDFI), contrast-enhanced CT ( CECT) and CEUS examinations were performed.A biopsy was performed on each of positive lesions . Results A total of 12 positive lesions were detected by CECT , and the biopsy proved to be residual tumor .A total of 11 lesions were detected by CEUS (the rate of missed diagnosis was 8.3%, 1/12). In CEUS positive lesions, 8 lesions were detected by CDFI (the rate of missed diagnosis was 33.3%, 4/12).There were no false positives. Conclusions Application of CEUS to evaluate the effect of liver tumor ablation is simple , reliable, and non-radiative.It has obvious advantages in follow-ups after liver tumor ablation and guided biopsy and treatment of residual lesions .
