Area of Science:

  • Orthopedics
  • Radiology
  • Neurosurgery

Background:

  • Cervical spine imaging often lacks dynamic assessment.
  • Understanding functional spinal cord mechanics is crucial for diagnosis.

Purpose of the Study:

  • To introduce a novel device for dynamic functional MRI of the cervical spine.
  • To evaluate the utility of this device in various cervical spine pathologies.

Main Methods:

  • Developed a device for MRI in five degrees of cervical spine flexion.
  • Utilized T1 and T2* weighted Fast Field Echo (FFE) sequences.
  • Performed dynamic functional MRI on 36 subjects (5 healthy, 31 patients).

Main Results:

  • The device facilitated detailed visualization of spinal cord and bony/ligamentous structures during flexion.

Related Experiment Videos

  • Dynamic imaging proved particularly effective in assessing whiplash injuries, spinal stenosis, and post-surgical changes.
  • Relationships between the spinal cord and surrounding structures were clearly depicted across different flexion angles.

    • Conclusions:

    • The developed device enables effective dynamic functional MRI of the cervical spine.
    • This technique offers valuable insights into the biomechanics of the cervical spine in various pathological conditions.
    • Dynamic functional MRI is a promising tool for evaluating spinal cord-ligamentous-bony interactions in flexion.
