Feasibility of percutaneous vertebroplasty with MR-guided laser ablation

This work was aimed at exploring the feasibility of MR-guided laser interstitial thermal therapy (LITT) as an adjuvant to vertebroplasty, especially for the management of spinal metastatic tumors. Such a technique may provide a number of advantages including an additional tool for tumor reduction, improved hemostasis, and high precision and safety in thermal therapy. We report on the development of tools and procedures to facilitate augmentation of vertebroplasty with LITT, and we describe the results of laser thermal treatments in normal canine vertebrae.
