Brain Surgery More Precise with Intraoperative MRI

Delicate brain surgery has become even more precise thanks to the addition of a high-field strength intraoperative MRI (iMRI) at Barnes-Jewish Hospital and Washington University School of Medicine.

This iMRI is the most advanced technology available.

The new intraoperative MRI has enhanced the abilities of Washington University neurosurgeons led by Ralph Dacey, MD, chairman of neurological surgery, and Michael Chicoine, MD, director of Intraoperative MRI, to offer innovative care and expand the body of knowledge in neuroscience. It also offers patients
new options.

The intraoperative MRI suite is a key part of the newly constructed eight-room neurosurgery area. The iMRI offers real-time diagnostic-strength (1.5 teslas) MRI visualization of the brain during surgery. It also provides a clearer, more detailed view of tumors and tumor margins during resections and enhanced visualization of seizure-producing and healthy brain tissue during epilepsy surgery. Integrated audio-visual and information management let surgeons compare the intraoperative scans to previous scans and records, and to videoconference and consult with other experts during procedures. The iMRI also reduces the need for follow-up MRI and possible repeat surgery.
