Radiofrequency ablation (RFA) is an alternative treatment for early-stage hepatocellular
carcinoma (HCC). The production of gas bubbles by RFA indicates threshold temperature of …

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

Abstract Radiofrequency (RF) ablation (RFA) is the most commonly used minimally invasive
procedure for thermal ablation of liver tumors. Ultrasound not only provides real-time …

Radiofrequency ablation (RFA) is increasingly being used as percutaneous treatment of
choice for patients with early stage hepatocellular carcinoma (HCC). An accurate …

Background/Aims: B-mode ultrasound (US) has difficulty targeting small hepatocellular
carcinomas (HCCs) with poor conspicuity during radiofrequency ablation (RFA). Contrast …

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: To compare contrast-enhanced computed tomography (CT) and contrast-
enhanced ultrasound (CEUS) for the quantitative evaluation of an ablation defect following …

Background & Aims. To investigate the value of dynamic three‐dimensional contrast‐
enhanced ultrasound (3D‐CEUS) in the assessment of therapeutic response of …

Purpose: To assess the added value of depicting tumour microvascularisation, using
dynamic contrast enhanced (CEUS), during radiofrequency ablation, as a means of …

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