Safety, efficacy, and functionality of high-field strength interventional magnetic resonance imaging for neurosurgery.

摘要: Objective Interventional magnetic resonance imaging (MRI) allows neurosurgeons to interactively perform surgery using MRI guidance. High-field strength (1.5-T) permits exceptional observation of intracranial and spinal pathological features. The development this technology its application a variety neurosurgical procedures are described. Methods We report on the first 101 cases that were treated in interventional unit (between January 1997 September 1998). These included 39 brain biopsies, 30 tumor resections, 9 functional cases, 8 cyst drainages, 5 laminectomies, 10 miscellaneous cases. Patients ranged age from 14 months 84 years (median, 43 yr); 61 patients male 40 female. Intraoperative techniques used influence surgical decision-making spectroscopy, MRI, angiography venography, chemical shift imaging, diffusion-weighted imaging. All was performed MRI-compatible instruments within 5-gauss line conventional outside line. Results biopsies yielded diagnostic tissue. Of 24 (80%) considered radiographically complete. incidence serious complications low comparable associated with operating rooms. One patient developed Propionibacterium acnes abscess 6 weeks after another experienced Staphylococcus aureus scalp cellulitis biopsy, yielding an infection rate less than 2%. No clinically significant hemorrhage observed immediate postoperative scans, although one delayed hematoma thalamotomy. stroke resection hippocampal tumor. untoward events instrumentation or intraoperative monitoring. Conclusion is safe effective for assisting achieving goals surgery. Preliminary results suggest capabilities can yield data significantly decision-making. rates complications, such as infection, new low.
