Rapid MRI of the spine in neonates with spinal dysraphism

Abstract Background The use of non-sedated T2-weighted Half-Fourier Acquisition Single-shot Turbo spin Echo (T2 HASTE) magnetic resonance imaging (MRI) sequences in screening for spinal cord syrinx in neonates with spinal dysraphism has not been reported in the literature. Objective To review our experience using T2 HASTE imaging of the spine (i.e., rapid spine MRI) in non-sedated neonates for detecting spinal cord syrinx in neonates with spinal dysraphism. Materials and methods We performed a retrospective search of our radiology database for neonates with spinal dysraphism who had rapid spine MRIs between May 2017 to February 2020. The images were reviewed in conjunction with clinical findings and standard spine imaging, when available. Results Thirty studies (in 29 neonates) fulfilled our inclusion criteria. Of the twenty-six neonates with myelomeningocele, 5 (19%) had spinal cord syrinx identified on neonatal rapid spine MRI. An additional two patients developed syrinx by two years of age. Potential pitfalls identified in interpreting rapid spine MRIs include motion artifacts and distinguishing a severe holocord syrinx from a truncated spinal cord. Conclusion Rapid spine MRI acquired without sedation or anesthesia may be used as a screening technique to detect spinal cord syrinx in neonates with spinal dysraphism.
