Abstract: Objective The purpose of this study was to investigate the application of contrast-enhanced ultrasound (CEUS) in differential diagnosis of hepatocellular carcinoma (HCC) and liver metastases (LM). Methods 77 patients with HCC (79 foci) and 40 patients with LM (41 foci) were recruited in our hospital, and routine sonography and CEUS were conducted. Results The enhancement type I, type II and type III in patients with HCC were 2.5%, 26.6% and 70.9%, significantly different as compared to 36.6%, 9.8% and 53.7%, respectively, in patients with LM (P<0.05); the peak time of enhancement and the time of washing out in HCC foci were (29.16±7.87)s and (51.89±22.80)s, significantly different as compared to 【(25.98±5.30) and (37.49±10.68)s, respectively, P<0.05 】 in LM foci. Conclusion The performance of CEUS in differentiating HCC and LM foci is efficacious, which might be helpful in clinical practice.
