Image-Guided Percutaneous Ablation of Renal Tumors
Renal tumors account for more than 50,000 new cases annually in the United States with a rising incidence (Chow et al., 1999). This is mainly because of an increase in diagnosis due to widespread use of cross-sectional imaging (Pantuck et al., 2001). Renal cell carcinoma constitutes 4% of all adult malignancies (American Cancer Society, 2008) and about 70 to 80 percent of patients presenting wi...
متن کاملRadiofrequency ablation of unresectable hepatic tumors.
PURPOSE To evaluate the efficacy and safety of radiofrequency ablation (RFA) in the treatment of primary and metastatic liver malignancies. MATERIALS AND METHODS Twenty-nine consecutive patients who have primary (n=9) and metastatic (n=20) liver malignancies were treated with RFA. The total number of lesions were 62 at the initiation of treatment and 28 new lesions were diagnosed at the follo...
متن کاملTrajectory optimization for the planning of percutaneous radiofrequency ablation of hepatic tumors.
Radiofrequency ablation is increasingly used in the treatment of hepatic tumors. Planning the percutaneous intervention is essential and particularly difficult. In this paper, we focus on an automated computation of optimal needle insertion in computer-assisted surgery with 3D visualization. First, we review our method which delineates on the skin of a virtual patient the candidate zones for ne...
متن کاملHepatic tumors treated with percutaneous radio-frequency ablation: CT and MR imaging follow-up.
PURPOSE To describe the appearance of hepatic tumors treated with radio-frequency (RF) ablation on computed tomographic (CT) and magnetic resonance (MR) images and the pattern of residual tumor at the site of RF ablation and to assess prospectively the sensitivity, specificity, and positive and negative predictive CT and MR imaging values in the evaluation of RF treatment. MATERIALS AND METHO...
متن کاملCost-effectiveness of percutaneous radiofrequency ablation for malignant hepatic neoplasms
Health technology The health technology examined in the study was radiofrequency (RF) ablation, a minimally invasive technique for the treatment of malignant liver neoplasms, in particular hepatocellular carcinoma (HCC) and colorectal liver metastases (CLM). Percutaneous RF ablation involves the insertion of one or more electrodes into the tumour nodule under imaging guidance. A high-frequency ...
