RESUMO
Objective: To show implementation and development of an operating room in which we operated 83 patients using intraoperative MRI (REMAIN). Method: We used a side-opening-magnet, 0.23 Tesla, installed in a surgical area specially designed with all the advances of the modern operating rooms. Results: A great variety of neuro-surgical procedures can be made with REMAIN controls. The obtained images are clear, without devices and with an excellent definition of the anatomical structures and the pathology, that allows the neurosurgeon to make more precise and safer interventions. Conclusions: The images of REMAIN in a surgical scope, make possible that injuries can be identified and located with absolute precision. It is particularly useful in determining with exactitude the tumor-like limits, optimizing the surgical approaches, obtaining complete extirpations of brain injuries and controlling the possible intraoperative complications.
