Abstract
- Objective: To report the preliminary experience in clinical application of 3.0 T intraoperative magnetic resonance imaging (iMRI) neuronavigation system in China.<br />Methods: From September 2010 to March 2011, a consecutive series of 122 patients with intracranial lesions underwent operations in guidance with 3.0 T iMRI. A retrospective analysis was conducted regarding clinical efficiency.<br />Results: Among 122 procedures, the numbers of intraoperative scanning were 2 - 4 times with an average of 2.6. The qualities of images were excellent. Due to the discovery and further possibility of resection of residual tumors, the ratio of gross total resection was increased from 71.7% to 90.0% in cerebral gliomas (n = 60), while from 75.9% to 93.1% in macroadenomas (n = 29). There were 6.7% of all patients occurred postoperative paralysis, but only 3.3% of patients had persistent paralysis at 1 - 2 months follow-up. There was no iMRI-related adverse event occurred. During the same period, more than 2500 patients underwent diagnostic MRI scanning.<br />Conclusions: 3.0 T iMRI neuronavigation system provides high-quality intraoperative structural, functional and metabolic images for real time tumor resection control and accurate functional preservation, resulting in an improvement in maximal safe brain surgery. The system is cost-effective.
