Intraoperative MRI (Io-MRI) may help to identify the borders of pathologic lesions intraoperatively and correct the surgeon"s orientation. A cranial surgery using Io-MRI was first performed in Boston in 1995 by Black and his team. Many factors such as the possibility of assessment of the brain shift and the degree of surgical resection, as well as evaluating the possibility of complications such as bleeding, infarction and edema during surgery were effective in the emergence of Io-MRI. There are two main Io-MRI designs: Boston and Heidelberg. In the design of Boston, all of the surgery is performed in the MRI device. In the Heidelberg design, the operating and imaging rooms are separated. GE, Siemens, Phillips, Medtronic and Hitachi are leaders of the Io-MRI industry. There are high technical barriers for new entrants in the industry. Io-MRI has been used successfully in both children and adults, not only in neuro-oncological surgery but also in neurovascular, spinal, stereotactic and functional surgery. Although Io-MRI is still expensive and requires extra safety conditions in the operating room, its use can be expected to become widespread with the rapidly advancing technology.
