IOUS and CE-IOUS during hepatic resection for patients with hepatocellular carcinoma in liver cirrhosis1.

Purpose: To retrospectively evaluate the role of intraoperative ultrasonography (IOUS) and contrast-enhanced IOUS (CE-IOUS) for the patients with hepatocellular carcinoma (HCC) undergoing hepatic resection (HR).

Methods: Twenty-one consecutive patients who had undergone HR for HCC were included in this study. The patients were subject to preoperative imaging modalities including preoperative ultrasonography (Pre-US) and preoperative contrast-enhanced ultrasonography (Pre-CEUS).

Comparison of the effectiveness and safety of ultrasound- and CT-guided percutaneous radiofrequency ablation of non-operation hepatocellular carcinoma.

To retrospectively compare the effectiveness and safety of ultrasound (US)- and computer tomography (CT)-guided percutaneous radiofrequency ablation (PRFA) in treating patients with non-operation hepatocellular carcinoma (HCC). Forty patients with non-operation HCC who were treated with US-guided PRFA (20 patients with 24 HCC lesions) or CT-guided PRFA (20 patients with 27 HCC lesions) were enrolled in this study. Follow-up was performed with US and CT/MRI.
