New Intraoperative MRI Advances Neurosurgery at MGH

Three-dimensional visualization of cerebral vasculature from CT angiography provides increased confidence in planning surgical intervention in life-threatening aneurysm cases. 3D views of MRI cortical surface and underlying tissues, with optional functional MRI fused with 3D anatomical display, enables neurosurgeons to plan procedures to spare crucial cortical areas, improve patient care and reduce operating room time.

Interventional Neuroradiology is an exciting, minimally invasive approach in the treatment of vascular diseases of the central nervous system. Conditions in the past that would have required surgical intervention such as aneurysms, vascular malformations, and tumors of the brain, spine, head and neck can be considered for treatment by using an endovascular approach to reach the lesion. Interventional techniques such as thrombolysis are also useful in the management of patients with acute ischemic stroke. These endovascular procedures can allow treatment of previously untreatable or difficult lesions.

fMRI Technique

Functional MRI maps functional areas preoperatively and noninvasively, so that the information may be used to help make decisions regarding the advisability of surgery and the optimal surgical approach. Preoperatively, it provides a three-dimensional surgical roadmap that can be studied by the neurosurgeon to help plan the procedure. Intraoperatively, it helps orient the neurosurgeon to both the structural and functional anatomy within the limited view of the craniotomy. When intraoperative mapping by direct cortical stimulation is still deemed necessary, it directs the surgeon to the regions of interest, and shortens the length of the procedure. Currently, the most common applications of presurgical fMRI are sensorimotor and language mapping. Presurgical functional brain mapping with fMRI is offered as a clinical service of the Division of Neuroradiology in the Department of Radiology at MGH.
