Magnetic Resonance Imaging

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...

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Neuroscience

Background:

  • Neuronavigation integrates functional and anatomical data, but pre-operative data acquisition leads to inaccuracies due to brain shift during surgery.
  • Accurate intraoperative visualization of brain structures and function is crucial for improving surgical outcomes.

Purpose of the Study:

  • To investigate advanced imaging and neurophysiological techniques for real-time intraoperative brain mapping.
  • To evaluate the technical aspects and safety of combining modalities like functional MRI (fMRI) and intraoperative MRI (ioMRI) with neurophysiology.

Main Methods:

  • Review of advancements in imaging technologies such as fMRI, MEG, and Intraoperative Optical Intrinsic Signal Imaging (IOIS).
  • Exploration of neurophysiological techniques and intraoperative MRI (ioMRI).
  • Focus on the combination of neurophysiology with ioMRI and intraoperative fMRI (ifMRI).

Main Results:

  • Established neuronavigation methods face limitations due to pre-operative data becoming inaccurate because of brain shift.
  • Emerging technologies like fMRI, MEG, IOIS, and ioMRI significantly impact neurosurgical precision.
  • Combining neurophysiology with ioMRI and ifMRI shows promise for enhanced intraoperative guidance.

Conclusions:

  • Real-time functional and anatomical data acquisition during surgery is essential to address brain shift limitations.
  • The technical feasibility and safety of integrating advanced imaging and neurophysiological modalities require thorough elucidation.
  • Further research into combined techniques like ioMRI and ifMRI can enhance neuronavigation accuracy and patient safety.
