Electromagnetic navigation to aid radiofrequency ablation and biopsy of lung tumors.

Purpose: We evaluated an electromagnetic (EM) navigation system (Veran Medical Technologies Inc, St. Louis, MO) to determine its potential to reduce the number of skin punctures and instrument adjustments during computed tomographic-guided percutaneous ablation and biopsy of lung nodules.

Description: Ten patients undergoing lung percutaneous ablation were prospectively enrolled.
