Better Than Radiofrequency Ablation
Cryoablation has a couple of advantages over another method, called radiofrequency ablation, says the study.
While cryoablation uses cold, radiofrequency ablation employs warmth. It heats a small area with electrical current from a radio wave, reducing pain signals from that spot.
Cryoablation is less painful for patients and easier for doctors to use with CT imaging, write the researchers. CT images provide a real-time look at the treatment area. "We can watch the ice ball form on CT as it is being done to ensure the appropriate area is being treated," says Dupuy in the news release.
Cryoablation was well-tolerated but needs testing on more people with longer follow-up, write the researchers, who are starting a new study of the procedure. Meanwhile, their first report appears in the March issue of the American Journal of Roentgenology.
