Photoacoustics, 2021 • March 10, 2021
This study demonstrates the feasibility of using photoacoustic time-frequency spectral analysis (PA-TFSA) to characterize bone mineral density (BMD) and bone microstructure. The results show that oste...
KEY FINDING: Osteoporotic bone samples with lower BMD and thinner MTT exhibit higher frequency components in PA-TFSA.
Photoacoustics, 2021 • March 10, 2021
This study introduces a new method, PA-PAS, for evaluating microvessel structures by mapping the acoustic power spectrum of photoacoustic signals along the azimuth direction. The method calculates the...
KEY FINDING: The intensity of photoacoustic signals from microvessels varies depending on the direction of measurement, with the strongest signals observed in the direction of the vessel's width.
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.
J Clin Densitom, 2015 • January 1, 2015
The study compares two methods for segmenting muscle from fat in pQCT scans: threshold-based edge detection and a watershed algorithm-guided manual segmentation. The watershed algorithm showed superio...
KEY FINDING: The watershed segmentation method demonstrated lower precision error compared to the threshold-based edge detection method across all participant groups.
PLoS ONE, 2014 • October 3, 2014
This study uses Autofluorescent Flavoprotein Imaging (AFI) to examine changes in spinal dorsal horn metabolic activity in a rat model of nerve-injury induced pain (Seltzer model) and the effect of spi...
KEY FINDING: Neuropathic rats demonstrated an AFI-response to palpation, while naı¨ve rats did not.
The Journal of Spinal Cord Medicine, 2016 • May 1, 2016
The study investigated the efficacy of using ultrasonography to measure rectal diameter and area as an additional parameter for evaluating neurogenic bowel in patients with spinal cord injury (SCI). T...
KEY FINDING: After defecation, the UMNB group had significantly smaller rectal diameters and areas compared to the LMNB group.
JOURNAL OF NEUROTRAUMA, 2017 • February 1, 2017
The study assessed brain activation during ankle movement in individuals with incomplete SCI compared to healthy controls using fMRI. Results showed that individuals with incomplete SCI exhibited incr...
KEY FINDING: Individuals with incomplete SCI showed increased brain sensorimotor activation during voluntary movement compared to healthy controls.
Pain, 2015 • January 1, 2015
This study aimed to identify subgroups of SCI patients based on thalamic Glx/Ins ratio and pain intensity and to compare their somatosensory function. Cluster analysis revealed two distinct groups: a ...
KEY FINDING: Participants with high neuropathic pain (HNP) showed significantly lower Glx/Ins ratios in the thalamus compared to those with low neuropathic pain (LNP).
BMC Musculoskeletal Disorders, 2016 • October 11, 2016
This retrospective study analyzed 101 patients with hip NMO using CT scans to assess osteomas and their relationship with surrounding tissues before surgery. The study found a strong correlation betwe...
KEY FINDING: CT scans accurately show the relationship between the abnormal bone and important structures like blood vessels and nerves.
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%.
