Dartmouth-Hitchcock Medical Centre inaugurates Visius surgical theatre


IMRIS announced that neurosurgeons at Dartmouth-Hitchcock Medical Centre in Lebanon, USA, have completed several cases to inaugurate use of intraoperative MRI (iMRI) within the Visius surgical theatre inside the hospital’s Centre for Surgical Innovation. The Centre for Surgical Innovation has the only operating suite in the world with both Visius iMRI and intraoperative CT (iCT) modalities able to serve multiple operating rooms without moving the patient.

The initial case – a revision right craniotomy for a meningioma – was also the first time Visius iMRI was used with next generation leading 3.0 tesla technology which includes applications to deliver better image quality with higher signal-to-noise ratio, faster 3-dimensional image acquisition, and improved ease-of-use and workflow.


“These first few cases have gone very well in terms of producing images during the cases and confirming that we have accomplished what we had  intended,” says David Roberts, Dartmouth-Hitchcock neurosurgery section chief and professor of surgery and neurology at the Geisel School of Medicine, who led the first case. “We expect the iMRI inside the Centre for Surgical Innovation will expand our vision beyond what we can see with the naked eye to reach diseased tissue that is sometimes located within challenging to navigate anatomy,” he adds. “The operating room suite will have a direct value to patients by allowing us to do surgery better than before.”
