Abstract：Objective To evaluate the value of contrast-enhanced ultrasound (CEUS) guided biopsy in hepatic lesions.Methods A total of 33 patients with 35 lesions underwent contrast-enhanced ultrasound guided biopsy from Jan 2016 to Jan 2017 were enrolled in this study.Guided by contrast-enhanced ultrasound,the puncture site and needle path were selected and guided real-time biopsy was performed.Puncture successful rate and diagnostic accuracy were calculated.Results All the patients were performed successfully,and each lesion was punctured twice.The puncture successful rate was 100.0％.Among 33 patients,28 cases were diag nosed with malignancies (13 cases of hepatocellular carcinoma,10 cases of cholangio cellular carcinoma,3 cases of neuroendocrine carcinoma,1 case of metastatic urothelial carcinoma and 1 case of metastatic squamous cell carcinoma),and 5 cases were benign(2 cases of inflammatory lesions,hepatocellular adenoma in 1 case and dysplasia nodules in 2 cases).The diagnostic accuracy was 100.0％.Puncture complication was found in 1 case (small amount of bleeding under hepatic capsule).Conclusion Contrast-en hanced ultrasound can clearly display intrahepatic lesions,and real-time biopsy can improve the positive rate of puncture diagnosis.
