Figure 1. First generation 1.5 Tesla intraoperative MRI surgical suite. Figure 2. 3 Tesla intraoperative MRI surgical suite showing the surgical “pit” in the foreground. This design necessitated that all instrumentation entering the surgical suite had to be MRI-compatible. This suite design enhanced surgical throughput since it was no longer necessary to rotate the surgical table in order to dock with the magnet couch prior to obtaining intraoperative imaging [2, 3]. Before imaging, the removal of surgical instrumentation was not necessary. The only ferromagnetic surgical instruments that are utilized in this suite are the plastic-handled scalpel and the suture needles. The last in-line suite design has three rooms in which the 3T magnet is centrally located. A conventional surgical suite is sited to one side of the magnet with a biplane 30
angiography suite with surgical capabilities located on the other side. Surgery can be performed in all of these three rooms simultaneously. Diagnostic imaging can be performed while the angiography and surgical suites are in use. Once said diagnostic imaging is completed, the suite can be utilized for surgical imaging of patients from either side. The magnet is designed such that the patient can enter the magnet for imaging from either side. Ferromagnetic instruments can be used in the surgical and angiography suites but must be removed before the patient is transported into the room housing the magnet. We feel that this last design offers the greatest degree of flexibility because it will expand the imaging capabilities for the investigation of patients with vascular diseases, including stroke with cerebral angiography, diffusion and perfusion weighted imaging, MR angiography, and MR venography. By evaluating patients promptly following a vascular event, it is hoped that intervention can be implemented that may result in arresting or reversing neural injury that leads to an improved clinical outcome for the patient. Interventions could include thrombolytic therapy for embolic disease, administration of calcium channel blockers for vasospasm, or repositioning an aneurysm clip in the face of cerebral ischemia. Conclusion Based on the increasing number of units that have become operational since the inception of the technology in 1994, it is with relative certainty that ioMRI is now recognized as a useful adjunct to performing neurosurgery that can enhance the surgical outcome and ultimately result in a decreased length of stay for the patient with subsequent lower medical costs.
