Tumor resection in a shared-resource magnetic resonance operating room: experience at the University of Cincinnati.
BACKGROUND
At the University of Cincinnati, we have developed a shared-resource magnetic resonance operating suite that facilitates performance of both neurosurgical and diagnostic procedures in a single unit.


METHODS
The shared-resource magnetic resonance operating suite utilizes a Hitachi AIRIS II, 0.3-T, vertical field, open MRI unit located in the MROR. This magnet can be used for both diagnostic and interventional procedures. The addition of a rotating-operating table permits neurosurgical procedures to be performed outside of the 5-G line using standard neurosurgical equipment and operating microscopes.


RESULTS
We review our results with the shared-resource magnetic resonance operating room including the tabulated results from 30 transsphenoidal procedures and 63 glioma procedures. In addition, 2832 diagnostic procedures have been performed in the first 4 years of use.


CONCLUSIONS
The shared-resource intraoperative MRI facility produces high-quality intraoperative imaging studies, equal to those of high-resolution magnets, and is valuable in enabling the surgeon to achieve the planned degree of resection of glioma and pituitary tumors. The ability to perform diagnostic procedures in a shared unit has been a cost-effective solution for our institution.
