First study published on SyMRI on the spine
A study published in the American Journal of Neuroradiology (AJNR) is the first to apply SyMRI for the radiological examination of the spinal cord. The study assesses T1, T2 and PD values in cerebrospinal fluid (CSF), healthy as well as in desiccated intervertebral discs and vertebral bodies.
The authors believe that SyMRI could prove to be a good quantitative MR imaging technique for the assessment of the spinal cord, especially of the integrity of myelin and axons in posttraumatic or demyelinating lesions. Further, SyMRI could help classify disc degeneration, thus enabling clinicians to determine the degenerative state and choose the appropriate treatment. In addition, T1, T2, and PD values of vertebral bodies could be used in the detection of bone marrow conditions by providing a quantitative tool in ambiguous situations where visual determination of pathological changes is difficult.
The authors conclude that quantitative synthetic MRI will likely be implemented as part of the radiologist’s every day work. After setting the reference range for relaxation times of CSF, spinal cord, vertebral bodies and discs in healthy individuals, these measurements could be used in their future daily practice. Such an additional quantitative tool may help to assess various spinal conditions, classify disc degeneration and choose the appropriate treatment strategy for their patients.
Please note that SyMRI is not yet registered for use on the spine and these results do not guarantee regulatory approval.
