XXXX surgery evaluated by intraoperative low-field magnetic resonance imaging.

@entity11 @entity1 @entity5
OBJECTIVE: To give an overview on intraoperative magnetic resonance (MR) imaging in @entity11 surgery. MATERIAL AND METHODS: MR imaging was performed using a 0.2T scanner, located in a radiofrequency-shielded operating theatre. Two setups were used: surgery either in a neighbouring operating theatre, or directly at the 5G line. Additionally, in @entity11 adjacent to eloquent brain areas microscope- or pointer-based neuronavigation with integrated functional data was applied. 106 @entity11 were among the 330 @entity1 investigated in the last 5 years. RESULTS: We did not observe complications attributable to intraoperative MR imaging. Image quality was sufficient to evaluate the extent of the @entity5 resection in the majority of cases. Intraoperative imaging revealed remaining @entity5 in 63%. In a total of 26% @entity1 @entity5 could be removed due to the results of intraoperative imaging, increasing the rate of @entity5 removal especially in the low-grade @entity5 . The additional use of functional neuronavigation prevented an increased morbidity. CONCLUSION: Intraoperative MR imaging offers the possibility of @entity5 removal during the same surgical procedure in case of @entity5 remnants, increasing the rate of @entity5 removal. The effects of brain shift can be compensated for using intraoperative image data for updating.
