Control: No spinal cord injury

SCI-1: spinal cord injury and ASIA Grade A and B

SCI-2: spinal cord injury and ASIA Grade C

SCI-3: spinal cord injury and ASIA Grade D

Every patient needs an MRI to assess spinal cord injury. This is one of the clinically necessary examinations.

original MRI image format DICOM to Nii was based on Python (Version: 3.10.6), and those would be loaded into the MRIcroGMRI imageL software (Version: 12.2). Three spinal surgeons (with 5, 8 and 18 years of experience in interpreting spinal MRI respectively) manually depict the region of interest (ROI) of the lesion area layer by layer, to form three dimensional (3D) volume of interest (VOI). After the primary spinal surgeon finished depicting the injured spinal cord, the senior spinal surgeon checked the quality of ROI and made some adjustments.

ASIA scores means American Spinal Injury Association Impairment Scale. ASIA has 5 grades depends on the severity of spinal cord injury. Grade A :No sensory or motor function is preserved in sacral segments S4-S5, no sacral sparing. Grade B:Sensory but not motor function is preserved below the neurological level and includes sacral segments S4-S5, AND No motor function is preserved more than three levels below the motor level on either side of the body. Grade C: Motor function is preserved below the neurological level AND More than half of the key muscle functions below the neurological level of injury have a muscle grade of less than 3 (Grades 0-2). Grade D: Motor function is preserved below the neurological level AND At least half (half or more) of the key muscle functions below the neurological level of injury have a muscle grade ≥ 3. Grade E: If sensation and motor function are graded as normal in all segments AND the patient had prior SCI-related deficits.
