Background. Radiofrequency ablation (RFA) is a curative therapy for hepatocellular
carcinoma (HCC). In RFA, ultrasonography (US) is most commonly used to guide tumor …

Aim: During radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC), a
hyperechoic rim develops around the HCC nodules. The usefulness of the hyperechoic rim …

Background. Contrast‐enhanced CT is regarded as the gold standard for monitoring
radiofrequency ablation (RFA) of hepatocellular carcinoma (HCC). Recently, 3‐dimensional …

Objective: Contrast‐enhanced computed tomography (CECT) is regarded as the gold
standard for assessing the efficacy of radiofrequency ablation (RFA) against hepatocellular …

Purpose: To observe the visibility and changes in the echogenicity of ablated tumor and
ablated nontumor areas after radiofrequency ablation (RFA) over time using gray-scale …

OBJECTIVE: We investigated contrast-enhanced three-dimensional ultrasonography (CE
3D US) with contrast agent Sonazoid for evaluating the effect of percutaneous …

Purpose Contrast-enhanced ultrasound (US) has been shown to be an efficient imaging
modality in guiding radiofrequency (RF) ablation of hepatocellular carcinomas (HCC). The …

Objective Local recurrence after radiofrequency ablation (RFA) is a major problem that
needs to resolved to increase the survival rate of hepatocellular carcinoma (HCC). CE-US …

Percutaneous radiofrequency ablation (RFA) is an established nonsurgical curative
treatment for hepatocellular carcinoma (HCC). Because of its efficiency and safety …

Results It was possible to obtain accurate position of the needle during RFA procedure in all
12 nodules. The needle was confirmed to be inserted into the center of the tumor nodule by …
