Neurosurgery & Interventions in a VISIUS Surgical Theatre using Intraoperative MR Imaging & X-ray Angiography

Clinical Applications

  • Neurosurgery
  • Cerebrovascular Interventions
  • Cardiovascular Intervention

For neurosurgery, neurovascular, and cardiovascular interventions, a high-field MR scanner travels into the OR on-demand to provide intraoperative images of diagnostic quality – without introducing additional risk to the patient – delivering real-time information to clinicians while preserving optimal surgical access and techniques.  With seamless transitions between MR and angio systems, a VISIUS Surgical Theatre enables open surgical and catheter-based treatments and real-time assessment of therapy in a single integrated suite.

Enhanced Intraoperative Vision

The combination of imaging modalities in a VISIUS Surgical Theatre maximizes intraoperative vision for the clinician.  MR imaging provides visualization and enhances assessment of soft tissue and anatomical structures.  Fluoroscopy and/or angiography provides visualization of vessels and guides catheters and placement of devices.

Streamlined Workflow

The single integrated system in a VISIUS Surgical Theatre eliminates patient transport between imaging modalities and streamlines workflow.  After MR scanning, the patient can be transitioned to image-guided intervention on the angiography system without moving the patient from the table. During and immediately after the procedure, new MR images can be taken to assess treatment and to determine if further intervention is required.

Intraoperative Imaging Without Added Risk

Combining modalities enhances the clinician’s vision and precision of treatment without adding risk in the OR.  In fact, the risk associated with patient transport between rooms is eliminated.  The availability of MR imaging on-demand, creates opportunities to reduce risk:

  • By using MR instead of CT perfusion to assess potential stroke, the patient is not exposed to ionizing radiation
  • By using MR imaging for 3D images, clinicians can bypass fluoroscopy and the associated radiation and contrast

Configurations | IMRIS

In a two-room configuration, a theatre for surgery and/or interventions is adjoined to either a magnet bay, where the MR remains until needed for intraoperative imaging, or a complete diagnostic room where the MR can be used for diagnostic imaging. VISIUS Surgical Theatre can be configured in two-room and three-room configurations to suit a wide range of clinical applications and to maximize utilization of the space and equipment.
