Intraoperative MRI Scanner (IMRIS)

Magnetic Resonance Imaging, or MRI, allows surgeons to distinguish a tumor from healthy tissue and helps them determine if they have successfully removed all of a tumor. In the past, surgeons had to rely on MRI images taken before surgery, and then wait until after surgery to confirm the entire tumor was removed. With an intraoperative MRI scanner (IMRIS), an MRI can be performed during surgery, right in the operating room. This lets neurosurgeons see real-time images of the brain, so they can check the progress of surgery and make adjustments as necessary.

Indiana University Health Methodist Hospital is the only hospital in the state that can provide this revolutionary technology. The IMRIS moves back and forth on rails between two integrated operating rooms, allowing surgeons to bring the MRI technology to the patient, rather than moving the patient. This can be particularly helpful for people who are in critical condition. This advanced technology helps neurosurgeons at Indiana University Health Neuroscience safely remove more of a tumor, and reduce the need for follow-up surgery. The IMRIS also enables neurosurgeons to avoid critical areas by allowing them to see more sections of the brain during surgery.

Currently, fewer than 40 hospitals worldwide feature the IMRIS technology.
