Magnetic resonance imaging therapy. Intraoperative MR imaging

Area of Science:

• Neurosurgery
• Medical Imaging
• Surgical Technology

Background:

• Image-guided neurosurgery aims to improve accuracy and safety by integrating advanced imaging modalities into the operating room.
• Traditional neurosurgery often relies on preoperative imaging, which may not accurately reflect intraoperative conditions.
• The need for real-time imaging and navigation during complex neurosurgical procedures is critical for expanding treatable lesions.

Purpose of the Study:

• To design and implement an open-configuration Magnetic Resonance Imaging (MR) suite for intraoperative neurosurgery.
• To enable real-time MR imaging within a surgical suite without patient repositioning.
• To facilitate online image-guided stereotaxy and real-time instrument tracking during neurosurgical operations.

Main Methods:

• Development of an open-configuration MR imaging suite through collaboration between General Electric Corporation and Brigham and Women's Hospital.
• Integration of real-time, intraoperative MR imaging capabilities within the surgical suite.
• Implementation of online stereotactic guidance and instrument tracking registered to intraoperative MR images.

Main Results:

• Successful implementation of an open-configuration MR suite enabling intraoperative MR image acquisition.
• Demonstration of online image-guided stereotaxy without the need for preoperative imaging.
• Real-time tracking of surgical instruments within the operative field, registered to MR images.

Conclusions:

• The developed open-configuration MR imaging suite significantly enhances neurosurgical capabilities.
• Intraoperative MR imaging improves surgical accuracy, safety, and the scope of treatable lesions.
• This technology represents a significant advancement in image-guided neurosurgery.
