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

Figure 1  T2-weighted sagittal magnetic resonance imaging of the spine, where the highlighted region denotes the tissue bridge between adjacent vertebral segments.

Figure 2  Axial schematic of adjacent vertebral segments, demonstrating the comparison of intact (left) and altered (right) tissue bridge morphology together with associated vascular networks.

Figure 3 Flowchart depicting the workflow of tissue bridge assessment - from magnetic resonance imaging-based measurement (sagittal/axial imaging) through quantitative analysis (volume, length, connectivity) to the prediction of clinical outcomes (e. g., neurological function, motor/sensory recovery potential) and associated prognostic metrics.
