Evidence to Improve Care

Positional Magnetic Resonance Imaging for People with Ehlers-Danlos Syndrome or Suspected Craniovertebral or Cervical Spine Abnormalities


Ontario Health Technology Advisory Committee Recommendations

  • Given the current absence of evidence for the utility of positional magnetic resonance imaging (positional MRI), the Ontario Health Technology Advisory Committee recommends that positional MRI not be funded or considered generally accepted practice for the diagnosis or management of (a) spinal or craniovertebral abnormalities among individuals with Ehlers-Danlos syndrome, or (b) major craniovertebral or cervical spine abnormalities among symptomatic individuals.

Ehlers-Danlos syndrome is an inherited medical condition affecting the connective tissues (such as skin and joints) that help hold the body together. This condition can lead to loose and unstable joints, which may also cause severe pain and other problems in the spine or the craniovertebral junction (the place where the skull meets the spine). There are also several other conditions that can increase the risk of similar problems in the cervical (upper) spine and craniovertebral junction.


Health Quality Ontario Reviews Positional Magnetic Resonance Imaging for Specific Spinal Abnormalities

Positional MRI is a newer type of diagnostic imaging that allows patients to sit, stand or take other positions throughout the scanning process. Some experts believe patients with Ehlers-Danlos syndrome or suspected cervical spine or craniovertebral abnormalities might benefit from this technology because it might better detect abnormalities only visible when the patient is upright. Appropriate imaging and diagnosis is important to determine the best way to manage and treat these conditions.
