Percutaneous radiofrequecy ablation (RFA) is becoming a standard minimal invasive procedure in the clinical routine. However, the control of shape and size of the ablation zone is unsatisfactory, especially close to large vessels. In this work, our aim is to present a novel image based, fast approximation of the ablation zone with respect to the cooling blood flow, which decreases thermal ablat...
CONTEXT There is little reported experience of radiofrequency ablation of pancreatic tumours. Our group has reported the development of a porcine pancreatic model of radiofrequency ablation of the pancreas. This brief report details the application of this technique to clinical practice. CASE REPORT A 58-year-old man with metastatic pancreatic tumour underwent operative radiofrequency ablatio...
Image-guided tumor ablation provides curative treatment in properly selected patients or appropriate therapeutic options whenever surgical techniques are precluded. Tumor response assessment post ablation is important in determining treatment success and future therapy. Accurate interpretation of post-ablation imaging findings is crucial for therapeutic and follow-up strategies. Computed Tomogr...
Previous work indicated that ultrasound echo decorrelation imaging can track and quantify changes in echo signals to predict thermal damage during in vitro radiofrequency ablation (RFA). In the in vivo studies reported here, the feasibility of using echo decorrelation imaging as a treatment monitoring tool was assessed. RFA was performed on normal swine liver (N = 5), and ultrasound ablation us...
OBJECTIVE To report rates of amenorrhea and treatment failure after global endometrial ablation and to estimate the association between patient factors and these outcomes by developing and validating prediction models. METHODS From January 1998 through December 2005, 816 women underwent global endometrial ablation with either a thermal balloon ablation or radio frequency ablation device; 455 ...
BACKGROUND Luminal esophageal temperature (LET) monitoring is one strategy to minimize esophageal injury during atrial fibrillation ablation procedures. However, esophageal ulceration and fistulas have been reported despite adequate LET monitoring. The objective of this study was to assess a novel approach to LET monitoring with a deflectable LET probe on the rate of esophageal injury in patien...
