Magnetic resonance imaging tissue bridges: An emerging biomarker for prognostication in traumatic spinal cord injury

Traumatic spinal cord injury (SCI) remains one of the most challenging conditions in neuro-orthopedics, and functional recovery outcomes are mainly unpredictable. A recent prospective study provided compelling evidence that quantitative magnetic resonance imaging biomarkers, particularly midsagittal tissue bridge dimensions, could serve as valuable predictors of neurological recovery following acute SCI. By correlating tissue bridge measurements at 1 month and 6 months with motor and sensory improvements, a clinically meaningful imaging-based prognostic model was developed. Moreover, the inverse association among canal compromise, lesion size, and functional outcomes highlighted the importance of early structural preservation in SCI management. This study emphasized the growing potential of magnetic resonance imaging as both a diagnostic and prognostic tool, with significant implications for patient stratification in clinical and research settings. Future research incorporating tissue bridge biomarkers with advanced imaging techniques and neuroregenerative therapies may further refine personalized rehabilitation strategies for SCI patients.
