High-Resolution MRI Evaluation of Neonatal Brachial Plexus Palsy: A Promising Alternative to Traditional CT Myelography

Abstract: BACKGROUND AND PURPOSE:Despite recent improvements in perinatal care, the incidence of neonatal brachial plexus palsy remains relatively common. CT myelography is currently considered to be the optimal imaging technique for evaluating nerve root integrity. Recent improvements in MR imaging techniques have made it an attractive alternative to evaluate nerve root avulsions (preganglionic injuries). We aim to demonstrate utility of MR imaging in the evaluation of normal and avulsed spinal nerve roots.

“…Magnetic Resonance Imaging (MRI) is being used more frequently as an imaging tool since it is less invasive than a CT myelogram. 44 Somashekar et al 42 used MRI imaging in a small sample, to detect root avulsions at an overall sensitivity of 75% and specificity of 82%. Finally, non-invasive ultrasound provides information on nerve, GH joint and muscle integrity thus can aide in pre-microsurgical planning.…”

“…One exception is the assessment of the cervical spine in brachial plexus injuries, when considering nerve root avulsion. CT myelography and MRI have a diagnostic accuracy of 70% to 95%, when looking for a pseudomeningocele and possible root avulsion 16. The sensitivity of detection of cervical nerve root avulsion is reported to be 93% for both MR and CT myelography 17.…”
