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.
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).
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.
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).
BioMed Research International, 2021 • January 27, 2021
This study explored the feasibility of using low-intensity pulsed ultrasound (LIPUS) to treat fracture nonunion while monitoring for heterotopic ossification (HO) using ultrasonography. The results de...
KEY FINDING: LIPUS therapy facilitated fracture repair in a patient with nonunion, as evidenced by ultrasound and radiographic outcomes showing callus formation and a blurred fracture line.
Neural Plasticity, 2021 • February 2, 2021
This study used VBM and graph theoretical network analyses to investigate alterations in GMV and GMV-based SCNs in complete thoracic SCI patients within one postinjury year, and partial correlation an...
KEY FINDING: SCI patients showed reduced gray matter volume in the left middle frontal cortex, right superior orbital frontal cortex (OFC), and left inferior OFC.
Scientific Reports, 2021 • March 15, 2021
This study introduces Orientation Selective Epidural Spinal Cord Stimulation (OS-ESCS) in rats and uses fMRI to monitor brain activations during stimulation of spinal segments S1 and L2. The findings ...
KEY FINDING: OS-ESCS modulates spinal-brain connectomes within the CNS, as demonstrated by brain activations during stimulation of S1 and L2 spinal segments.
Journal of Medical Ultrasound, 2022 • July 1, 2022
This study investigated the acute ultrasonographic changes in lower extremity muscle structure in patients with motor complete spinal cord injury (SCI). The researchers found a decrease in the thickne...
KEY FINDING: There was a significant decrease in rectus femoris muscle thickness over the 4-week study period.
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.
NeuroImage: Clinical, 2023 • March 10, 2023
This systematic review and meta-analysis investigated spinal cord atrophy following spinal cord injury (SCI) using MRI measurements of the cervical spinal cord cross-sectional area (cSC CSA). The stud...
KEY FINDING: The meta-analysis revealed a significant reduction in cSC CSA in individuals with SCI compared to controls, with a standardized mean difference of -1.48, indicating substantial atrophy.
