Summary
Preoperative MRI signal intensity does not predict recovery in spinal cord injury without radiographic evidence of trauma (SCIWORET). However, older age is a key factor for poor neurological recovery after surgery.
Area of Science:
- Neurosurgery
- Radiology
- Orthopedics
Background:
- Spinal cord injury without radiographic evidence of trauma (SCIWORET) presents diagnostic challenges.
- Predicting neurological recovery is crucial for patient management and surgical decision-making.
Purpose of the Study:
- To assess the prognostic value of preoperative T2-weighted MRI increased signal intensity (ISI) grade in SCIWORET patients.
- To identify risk factors for poor neurological recovery following surgical intervention in SCIWORET.
Main Methods:
- Retrospective cohort study of 128 SCIWORET patients undergoing surgery.
- Classification of patients into ISI grades (0, 1, 2) based on preoperative MRI.
- Neurological assessment using Japanese Orthopaedic Association (JOA) score and recovery rate (RR); multivariate logistic regression and ROC analysis.
Main Results:
- Increased signal intensity (ISI) was observed in 86.7% of patients.
- Higher ISI grades correlated with lower preoperative JOA scores but not with postoperative RR.
- Age > 58.5 years was the sole independent predictor of poor neurological recovery (RR < 50%).
Conclusions:
- Preoperative ISI grade indicates SCI severity but does not predict surgical outcomes in SCIWORET.
- Older age is a significant independent predictor of poorer neurological recovery.
- Integrating patient age into prognostic counseling and surgical planning is essential for SCIWORET management.

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
