Global and site-specific analysis of bone in a rat model of spinal cord injury-induced osteoporosis
Bone Reports, 2020 • January 1, 2020
This study introduces a global 2D morphometric analysis step into the μCT analysis process, providing a more systematic approach to VOI selection and enabling the acquisition of additional information...
KEY FINDING: SCI-induced osteoporosis was localized in trabecular bone, with metaphyseal bone more severely affected than epiphyseal bone.
Bone Infarct as an Indicator of Acute Spinal Ischaemia
Case Reports in Pediatrics, 2020 • February 27, 2020
This case report presents a rare instance of acute spinal cord infarction in a teenager following a minor trauma, initially presenting with normal MRI findings. The key to diagnosis was the identifica...
KEY FINDING: Initial MRI scans can be normal in cases of acute spinal ischemia, necessitating repeat imaging if symptoms persist.
Magnetic Resonance Imaging of Trunk Musculature and Intervertebral Discs in Patients with Spinal Cord Injury with Thoracolumbar Vertebral Fractures: A Prospective Study
Asian Spine Journal, 2020 • December 1, 2020
This prospective study evaluated trunk musculature and intervertebral discs in SCI patients with thoracolumbar fractures using MRI. The study revealed significant decreases in disc and trunk parameter...
KEY FINDING: Significant decreases were observed in disc parameters (disc angle, skin angle, CSA, disc height) and trunk parameters (trunk width, trunk depth, CSA of lumbar muscles) during the first 3 months after SCI.
Can a relatively large spinal cord for the dural sac influence severity of paralysis in elderly patients with cervical spinal cord injury caused by minor trauma?
Medicine, 2020 • June 26, 2020
This study aimed to determine if a relatively large spinal cord for the dural sac influences the severity of paralysis in elderly patients with cervical spinal cord injury (SCI) caused by minor trauma...
KEY FINDING: A significant negative correlation was observed between the JOA score (indicating severity of paralysis) and the spinal cord/dural sac ratio at the mid-C5 vertebral level.
Simultaneous voxel-wise analysis of brain and spinal cord morphometry and microstructure within the SPM framework
Hum Brain Mapp, 2021 • January 1, 2021
This study validated a simultaneous analysis tool (SPM-BSC) for brain and cervical cord MRI data within the SPM framework, comparing trauma-induced changes in SCI patients to healthy controls. The SPM...
KEY FINDING: The SPM-BSC approach identified trauma-induced changes in the sensorimotor system of the brain and spinal cord in SCI patients, consistent with findings from established analysis methods.
Axial MRI biomarkers of spinal cord damage to predict future walking and motor function: a retrospective study
Spinal Cord, 2021 • October 6, 2020
This retrospective study assessed whether axial damage ratios from MRIs could predict walking ability one year after spinal cord injury (SCI). The study found that axial damage ratios were significant...
KEY FINDING: Axial damage ratios from MRIs taken early after injury were significant predictors of walking ability one year post-SCI; smaller ratios correlated with a higher likelihood of walking.
Missed bilateral radial head fractures in central cord syndrome
Spinal Cord Series and Cases, 2020 • October 13, 2020
This case report highlights the potential for missed injuries, specifically bilateral radial head fractures, in patients presenting with traumatic central cord syndrome. The importance of a thorough t...
KEY FINDING: Bilateral radial head fractures can be missed in patients with traumatic central cord syndrome during initial trauma assessments.
Segmented quantitative diffusion tensor imaging evaluation of acute traumatic cervical spinal cord injury
Br J Radiol, 2020 • November 10, 2020
Abnormalities in DTI metrics of DTI-segmented white matter tracts were detected at the neurological level of injury relative to normal controls and levels remote from the injury site, confirming its ...
KEY FINDING: There were significant differences in FA between the level of injury and controls for total white matter (0.65 ± .09 vs 0.68 ± .07; p = .044), motor tracts (0.64 ± .07 vs 0.7 ± .09; p = .006), and combined motor/sensory tracts (0.63 ± .09 vs 0.69 ± .08; p = .022).
Correlation of Clinical Findings in Acute Spinal Injury Patients with Magnetic Resonance Including Diffusion Tensor Imaging and Fiber Tractography
Spine Surg Relat Res, 2020 • July 10, 2020
This study evaluated the role of diffusion tensor imaging (DTI) and fiber tractography in acute spinal injury, correlating imaging findings with clinical profile and neurological outcome in twenty-fiv...
KEY FINDING: Fractional anisotropy (FA) correlated significantly with the ASIA Impairment Scale (AIS), indicating that FA values reflect the severity of neurological deficits in SCI patients.
Effect of b Value on Imaging Quality for Diffusion Tensor Imaging of the Spinal Cord at Ultrahigh Field Strength
BioMed Research International, 2021 • January 6, 2021
This study investigates the influence of b value on diffusion tensor imaging (DTI) quality of rat spinal cords at 7T MRI. In this study, rats’ spinal cord DTI was performed under ultrahigh field streng...
KEY FINDING: Image signal-to-noise ratio (SNR) decreases as the b value increases, with the best image quality observed at b = 200 s/mm². The highest NMI result of the image appeared at b = 200 s/mm2 (0:381 ± 0:038) and the lowest at b = 1000 s/mm m2 (0:354 ± 0:044).
