Radiofrequency ablation of colorectal metastasis to lung

Dr Derek Glenn, Interventional Radiologist at St George Hospital in Sydney, demonstrates how to treat a lung lesion using the RITA RF ablation probe under CT fluoro guidance. This video demonstrates 1) locating the lesion, 2) choice of approach, 3) technique for positioning RF needle without irradiating the operators hands and 4) how to reduce ON time and hence patient dose. The CT Fluoro technique is a Real-Time method using 3 image display at 120kV and 20mA. This clip is part of a educational video series demonstrating proven techniques in the use of CT interventional guidance and Real-Time CT Fluoroscopy for various clinical conditions.
