Biol Psychiatry Cogn Neurosci Neuroimaging, 2021 • March 1, 2021
This study investigated the relationship between regional brain volumes, measured by MRI at 2 weeks post-mTBI, and PTSD outcomes at 3 and 6 months post-injury. Smaller volumes in the insula, superior ...
KEY FINDING: Smaller volumes of the superior frontal, rostral, and caudal anterior cingulate regions were individually predictive of PTSD at 3 months post-injury.
World Neurosurg, 2014 • December 1, 2014
Advanced spinal cord imaging has great potential to offer specific physiological details regarding cord integrity and health. Though advanced spinal cord imaging is still in early development and impl...
KEY FINDING: Conventional MRI may not consistently correlate with clinical findings post-SCI, prompting interest in microstructural and metabolic imaging.
PLoS ONE, 2012 • December 12, 2012
The study investigated the relationship between degeneration of the corticospinal tract (CST) in the cervical cord above a traumatic spinal cord injury (SCI) and its relationship with cervical atrophy...
KEY FINDING: In individuals with SCI, FA was significantly lower in both CSTs throughout the cervical cord and brain when compared with controls.
Arch Phys Med Rehabil, 2015 • April 1, 2015
This pilot study used fMRI to examine cortical activation during a visual illusory walking paradigm in persons with SCI compared to able-bodied controls. The results showed significant activation in t...
KEY FINDING: Persons with SCI showed significant activation in the somatosensory cortex during visually illusory walking.
Ann Rehabil Med, 2015 • June 1, 2015
This study used graph theoretical approaches to assess the efficiency of information processing in the whole brain network of patients with cervical incomplete SCI using rs-fMRI. The study found that ...
KEY FINDING: The normalized characteristic path length to random network was higher in SCI patients than in controls and reached statistical significance at 12%–13% of density.
Annals of Neurology, 2015 • November 1, 2015
This study demonstrated progressive atrophic and microstructural changes across the sensory system in patients with subacute SCI. These structural changes, observed via MRI, were closely related to se...
KEY FINDING: Patients with SCI showed progressive degenerative changes in cervical cord and brain morphometry across the sensory system compared to controls.
NeuroImage, 2017 • June 29, 2017
The study introduces reliability masking, a novel outlier rejection technique for spinal cord DTI, to supplement existing artifact correction methods. Reliability masking, when added to registration a...
KEY FINDING: Adding reliability masking to established post-processing steps increased the statistical power of clinical findings by 4.7%.
Asian Journal of Neurosurgery, 2015 • July 1, 2015
This prospective study correlated clinical profiles and neurological outcomes with imaging findings in 25 acute SCI patients. Imaging features from radiographs, CT, and MRI were analyzed and correlate...
KEY FINDING: Patients with complete SCI had significantly more compression percentage, maximum canal compromise and maximum spinal cord compression at presentation.
PLOS ONE, 2015 • October 30, 2015
This study presents a unique longitudinal dataset of weekly rs-fMRI scans over 3.5 years to assess the reproducibility and temporal structure of rs-fMRI outcome measures. The research identifies 14 RS...
KEY FINDING: Resting-state functional MRI (rs-fMRI) outcome measures, specifically network spatial maps, temporal signal fluctuation magnitude, and between-network connectivity (BNC), showed high inter-session reproducibility.
Korean J Radiol, 2015 • November 1, 2015
The study evaluated the diagnostic performance of DTI parameters (MD, LD, RD, FA) in patients with cervical spondylotic myelopathy (CSM) who had spinal cord compression but no signal changes on conven...
KEY FINDING: FA values were negatively correlated with the degree of central canal stenosis, while RD values showed a positive correlation.
