Merging multiple CT images (summation of CT scans) increases the accuracy of probe repositioning during radiofrequency ablation treatments of various lesions, according to a recent study performed at Dartmouth-Hitchcock Medical Center in Lebanon, NH.

"During radiofrequency ablation the probe often needs to be repositioned in order to effectively treat an entire lesion," said John M. Gemery, MD, author of the study. "During radiofrequency ablation it is hard to determine the areas that have already been treated when moving the probe around. "Looking at summated images of several CT scans allows one to quickly check where the ablation probe has been," he said.
