Body-Mounted Robotics for Interventional MRI Procedures

AbstractPercutaneous selective laser amygdalo-hippocampectomy (SLAH) procedure is a new minimally invasive alternative to surgical amygdalo-hippocampectomy that involves targeted, controlled laser energy deposition under real-time magnetic resonance imaging (MRI) monitoring within a dedicated “interventional MRI” suite. Technical feasibility, safety and initial efficacy results from our program are encouraging and indicate a potential for paradigm shift in future treatment of patients with exclusively or predominantly focal unilateral seizure onsets within the mesial temporal lobe. Several institutions are currently employing this technology and more long-term follow-up results on larger cohorts of patients are expected in the near future. This article reviews the principles of MRI-guided SLAH, procedure set-up and equipment, the detailed phases of intra-procedural MRI guidance and treatment monitoring, and the MRI appearance of the resultant thermal ablation zones. We conclude with a discussion of our institutional experience at Emory University with MRI-guided SLAH as one of the leading sites offering this state-of-the-art technology.

Background MRI is attractive for the guiding and monitoring of interventional procedures due to its high intrinsic soft tissue contrast and the possibility to measure physiologic parameters like flow and cardiac function. Method The current status of interventional MRI for the clinical routine was analyzed. Results The effort needed for the development of MR-safe monitoring systems and instruments initially resulted in the application of interventional MRI only for procedures that could not be performed by other means. Accordingly, biopsy of lesions in the breast, which are not detectable by other modalities, has been performed under MRI guidance for decades. Currently, biopsies of the prostate under MRI guidance are established in a similar fashion. At many sites blind biopsy has already been replaced by MR-guided biopsy or at least by the fusion of MR images with ultrasound. Cardiovascular interventions are performed at several centers for ablation as a treatment for atrial fibrillation. Conclusion Interventional MRI has been established in the clinical routine for a variety of indications. Broader application can be expected in the clinical routine in the future owing to the multiple advantages compared to other techniques. Key points Citation format
