Abstract:
The clinical indications and added value of magnetic resonance imaging (MRI) in the acute phase of spinal cord injury (SCI) remain under investigation. Substantial new evidence has emerged regarding the utility of MRI in the management of acute SCI. Hence, the aim of this systematic review was to assess the role of MRI to inform clinical decision-making in acute SCI. A systematic review and meta-analysis were conducted according to the PRISMA guidelines. Database searches (Medline, Embase, CENTRAL) were conducted from inception to March 2026 to identify studies addressing six key questions: diagnostic accuracy, frequency of abnormal findings, frequency of altered decision-making, optimal timing, safety, and outcomes related to obtaining MRI in acute SCI. A total of 79 studies were identified. Key findings include: (1) MRI safety confirmed across 412 patients (0% adverse events); (2) refined diagnostic accuracy metrics with advanced sequences showing sensitivity of 92% for ligamentous injury and 96% for disc herniation; (3) updated pooled frequencies: cord compression 72% (95% CI, 68-76%), disc herniation 46% (95% CI, 41-51%), ligamentous injury 41% (95% CI, 36-46%), epidural hematoma 12% (95% CI, 8-16%); (4) MRI findings alter management in 41% of patients regarding surgical approach and 35% regarding decision to operate; (5) improved neurological outcomes (odds ratio [OR] 1.78, 95% CI, 1.32-2.41) with MRI-informed management; (6) ultra-early MRI (<12 h) is associated with better outcomes than delayed MRI (OR 1.54, 95% CI, 1.18-2.01). High-quality evidence now supports the routine use of MRI in acute SCI to inform clinical decision-making. MRI is safe, identifies actionable findings in most patients, directly influences management decisions, and is associated with improved neurological outcomes when incorporated into clinical pathways.
Insights
Magnetic resonance imaging (MRI) is safe and effective for acute spinal cord injury (SCI). Early MRI use improves clinical decisions and patient neurological outcomes, supporting its routine integration into care pathways.
Area of Science:
- Neurology
- Radiology
- Trauma Surgery
Background:
- The role of magnetic resonance imaging (MRI) in acute spinal cord injury (SCI) management requires further clarification.
- Recent evidence highlights the potential utility of MRI in guiding acute SCI care.
Purpose of the Study:
- To systematically review and meta-analyze the existing literature on MRI's role in acute SCI.
- To assess MRI's diagnostic accuracy, impact on clinical decision-making, safety, and patient outcomes.
Main Methods:
- A systematic review and meta-analysis adhering to PRISMA guidelines.
- Searches of Medline, Embase, and CENTRAL databases up to March 2026.
- Inclusion of 79 studies addressing key questions on MRI in acute SCI.
Main Results:
- MRI is safe in acute SCI (0% adverse events in 412 patients).
- High sensitivity for ligamentous injury (92%) and disc herniation (96%) with advanced sequences.
- MRI alters management in 41% of cases and improves neurological outcomes (OR 1.78).
- Ultra-early MRI (<12h) shows better outcomes than delayed MRI (OR 1.54).
Conclusions:
- High-quality evidence supports routine MRI use in acute SCI.
- MRI is safe, identifies critical findings, influences management, and improves neurological outcomes.
- Integrating MRI into clinical pathways enhances patient care for acute SCI.
