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

key information

source: Health Quality Ontario

year: 2015


Given the current absence of evidence for the utility of positional magnetic resonance imaging (pMRI), OHTAC recommends that pMRI 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 and other congenital, developmental, or acquired disorders can lead to abnormalities within the spine and craniovertebral junction (CVJ). Appropriate imaging and diagnosis is needed to determine patient management and need for complex surgery. Positional MRI allows imaging of the spine or CVJ with patients in upright, weight-bearing positions as well as in combination with dynamic maneuvers. Imaging with pMRI could allow diagnosticians to better detect spinal or CVJ abnormalities than recumbent MRI or a combination of other available imaging modalities might allow.
