We have conducted a large-scale 14-year study that found laser ablation with MR guidance is very effective in the treatment of primary and metastatic liver tumors. We presented data from 1394 patients with 3725 lesions at the 2007 European Congress of Radiology. We have since ablated a total of 5041 lesions in 1954 patients. The two largest patient groups suffered from colorectal liver metastases and breast cancer liver metastases. More »

The hottest trend in interventional radiology is also its coldest. Improved technology and growing clinical experience have moved cryoablation into mainstream IR practice. More »

Data in the April issue of Radiology validate radiofrequency ablation as a safe and effective treatment alternative for inoperable patients with lung cancer. The study, the largest and longest to date, also suggests RFA provides better survival and disease control in these patients than does external-beam radiotherapy. More »

The use of high-intensity focused ultrasound for various therapeutic applications has continued to grow since Lynn et al first proposed it in 1942.1 Advances in medical imaging technology in the last two decades have led to its widespread use in both research and clinical practice for the treatment of benign and malignant tumors, hemostasis, uterine fibroids, and other conditions.

Cryotherapy is often portrayed as radiofrequency ablation's little brother. But the thermal ablation technique is proving safer and more effective than previously thought, according to several papers presented at the RSNA meeting. More »

The swift rise of percutaneous ablative interventions represents one example of the power of innovation-and how it can crush barriers that stand between discovery and adoption. More »

Radiofrequency ablation is a growing part of the practice established by interventional radiologist Dr. Paul Christy and his partners at Methodist Hospitals’ Interventional Radiology Center in Omaha. Most of their RFA practice focuses on lung tumors, but they also treat tumors of the liver and bone. The 13-person group includes one part-time and two full-time interventional radiologists, as well as medical oncologists, radiation oncologists, surgeons, and other specialists. More »

Interventional oncology is on the rise for several reasons. Cancer detection is increasing in our population as more imaging is done at an earlier stage. The technology is continuing to advance and improve. More »

The rapidly expanding field of tumor ablation now includes a variety of heat-based ablation modalities using laser, microwave, radiofrequency, and ultrasound energy sources. Among these, RF ablation has found the greatest clinical utility worldwide. More »
