Summary
Intra-operative MRI addresses brain shift in neurosurgery by updating pre-operative data. This technology enhances surgical navigation accuracy and patient outcomes.
Area of Science:
- Neurosurgery
- Medical Imaging
- Computer-Assisted Surgery
Background:
- Advanced 3D rendering and multimodal image co-registration are sophisticated.
- Pre-operative data in surgical navigation cannot account for intra-operative brain shift.
- Intra-operative imaging updates are crucial for accurate neurological surgery.
Purpose of the Study:
- To discuss the design, advantages, limitations, and applications of an intra-operative MRI system.
- To highlight the integration of imaging into neurosurgical procedures.
- To introduce an integrated platform for intra-operative visualization and navigation.
Main Methods:
- An open-configured, intra-operative Magnetic Resonance Imaging (MRI) system (Signa SP, 0.5 T) was developed and implemented in 1995.
- The system allows for real-time updates of structural information during surgery.
- Integration with the 3D Slicer platform for visualization and navigation was established.
Main Results:
- The intra-operative MRI system effectively addresses the challenge of brain shift.
- The system facilitates integration of imaging updates into surgical procedures.

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).
