The field of interventional oncology with use of image-guided tumor ablation requires standardization of terminology and reporting criteria to facilitate effective communication of ideas and appropriate comparison between treatments that use different technologies, such as chemical (ethanol or acetic acid) ablation, and thermal therapies, such as(More)
Image-guided tumor ablation has become a well-established hallmark of local cancer therapy. The breadth of options available in this growing field increases the need for standardization of terminology and reporting criteria to facilitate effective communication of ideas and appropriate comparison among treatments that use different technologies, such as(More)
Six existing minimally invasive techniques for the treatment of primary and secondary malignant hepatic tumors--radio-frequency ablation, microwave ablation, laser ablation, cryoablation, ethanol ablation, and chemoembolization--are reviewed and debated by noted authorities from six institutions from around the world. All of the authors currently believe(More)
Although radio-frequency (RF) ablation has been accepted as a promising and safe technique for treatment of unresectable hepatic tumors, investigation of its complications has been limited. According to the multicenter (1,139 patients in 11 institutions) survey data of the Korean Study Group of Radiofrequency Ablation, a spectrum of complications occurred(More)
UNLABELLED According to the American Association for the Study of Liver Diseases guidelines, percutaneous ethanol injection (PEI) is a safe and highly effective treatment for small hepatocellular carcinomas (HCC) and should be the standard against which any new therapy is compared. The primary purpose of this study was to identify survival benefit of any(More)
CONTEXT AND OBJECTIVE To evaluate the efficacy and safety of ultrasound (US)-guided percutaneous radiofrequency (RF) ablation for benign cold thyroid nodules as a nonsurgical therapeutic modality. DESIGN, INTERVENTION, AND PATIENTS: A total of 35 benign cold thyroid nodules in 30 euthyroid patients (M:F = 2:28; mean age 39.1 years) underwent percutaneous RF(More)
OBJECTIVE The purpose of this article is to evaluate the value of gadoxetic acid-enhanced hepatobiliary phase imaging and high-b-value diffusion-weighted imaging (DWI) for distinguishing well-differentiated hepatocellular carcinomas (HCCs) from benign hepatocellular nodules in patients with chronic liver disease using 3-T MRI. MATERIALS AND METHODS(More)
Although ethanol ablation has been successfully used to treat cystic thyroid nodules, this procedure is less effective when the thyroid nodules are solid. Radiofrequency (RF) ablation, a newer procedure used to treat malignant liver tumors, has been valuable in the treatment of benign thyroid nodules regardless of the extent of the solid component. This(More)
OBJECTIVE The aim of this study was to elucidate the minimal ablative margin for percutaneous radiofrequency ablation (RFA) of hepatocellular carcinoma (HCC) (> 2 and < 5 cm) needed to prevent local tumor progression using CT image fusion and a 3D quantitative method. MATERIALS AND METHODS From April 2005 to March 2007, we performed percutaneous RFA for(More)
Radiofrequency (RF) thermal ablation has shown promise as a technique for treating inoperable solid tumors involving the liver, kidney, adrenal gland, and lung. However, like all other imaging-guided interventional procedures, RF ablation involves some element of risk. Varying degrees of complications can be expected, depending on factors such as the organ(More)
