the imaging of hepatocellular carcinoma (hcc) is challenging and plays a crucial role in the diagnosis and staging of the disease. a variety of imaging modalities, such as ultrasound, computed tomography (ct), magnetic resonance imaging (mri) and nuclear medicine are currently used in evaluating patients with hcc. although the best option for the treatment of these cases is hepatic resection or...

PURPOSE Thermal tissue ablation with radio frequency energy is an experimental treatment of renal tumor. We report early results of an ongoing trial of percutaneous radio frequency ablation for small renal tumors. MATERIALS AND METHODS Patients with percutaneously accessible renal tumors were evaluated for radio frequency ablation. Tumors were solid on computerized tomography (CT), 3 cm. or l...

PURPOSE To evaluate the feasibility of a technique of MR-guided stereotactic radio frequency ablation, which was developed as a minimally invasive treatment for brain tumors, and to determine MR characteristics and sequential evolution of radio frequency lesions created to ablate brain tumors. METHODS Fourteen lesions in 12 patients with primary and metastatic brain tumors were treated with t...

OBJECTIVE To determine the relative effectiveness of second generation ablation techniques in the treatment of heavy menstrual bleeding. DESIGN Network meta-analysis on the primary outcome measures of amenorrhoea, heavy bleeding, and patients' dissatisfaction with treatment. DATA SOURCES Nineteen randomised controlled trials (involving 3287 women) were identified through electronic searches...

Radiofrequency ablation is a procedure used to destroy nerves. A radio wave produces an electrical current used to heat up a small area of nerves, and this stops or reduces pain signals from the area. There is not enough information from clinical studies to be certain that this works in most people. Because we don’t yet know that this works, the Company considers this treatment investigational ...

lower extremity venous varicosis is a very prevalent disease. approximately 15 - 25 percent of the general population suffer from some degree of this disease. in recent years many new and innovative treatments have been developed for the disease and nowadays customary treatments ( saphenous strapping and phlebotomy) are nearly obsolete. these new treatments include laser ablation, radio frequen...
