HealthDay News - Lung tumors safely treated by radiofrequency ablation in patients with a single lung
From the Focused Ultrasound Surgery Foundation & Fibroid ReliefA new research center for MR-guided focused ultrasound ablation at the University of Virginia is aiming to become a leader in translational and clinical research for emerging interventional procedures.
You can tell by the titles of special focus sessions planned for the 2008 RSNA that program committee chair Dr. Robert M. Quencer sees an opportunity to use the sessions to examine tough issues affecting clinical imaging practice.
Efficient planning that considers variables and prognostic factors proves vital in RF tumor ablation A group of radiologists from Seoul learned some important lessons from more than 3000 radiofrequency ablation procedures carried out in patients with hepatic tumors during the past decade.
Robotic tools that could one day perform surgery on battlefields, in space, and at remote locations with minimal human guidance use 3D ultrasound as a key component.
Pairing chemoembolization with radiofrequency ablation improved survival in patients with unresectable hepatocellular cancer, according to a multidisciplinary group based at Shangdong University in Jinan, China. Their study results demonstrated how tumor microarchitecture could be manipulated to boost localized therapy.
Tumor ablation is defined as the direct application of chemical or thermal therapies to achieve substantial tumor destruction. Modalities such as ethanol ablation, radiofrequency ablation, laser ablation, and cryoablation have been used widely, primarily for the management of hepatic neoplasms.
Ultrasound-guided radiofrequency is generally a safe treatment for liver masses and carries an acceptable level of risk, but patients with large tumors and baseline liver function impairment have a higher risk of complications, according to researchers in Taiwan.
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.
“I predict that lung radiofrequency ablation is going to be very big indeed,” said Dr. Alice Gillams at the beginning of her two presentations on Saturday examining factors influencing tumor recurrence and incidence of pneumothoraces.
