Brain and Spine, 2022 • December 29, 2021
This study comprehensively reviews experimental in vivo imaging setups used in SCI research to provide an up-to-date overview for researchers aiming to advance knowledge of spinal cord regeneration an...
KEY FINDING: Magnetic Resonance Imaging (MRI), including functional MRI (fMRI) and microstructural MRI, is used for morphological assessment, lesion volumetry, and evaluation of the blood-spinal-cord-barrier integrity.
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.
Neural Regeneration Research, 2015 • November 1, 2015
The study assessed the potential of diffusion tensor imaging (DTI) for quantitative assessment of compressed lumbosacral spinal nerve roots in patients with lumbosacral stenosis. DTI findings demonstr...
KEY FINDING: DTI showed thinning and distortion in 36 lumbosacral spinal nerve roots (49%) and abruption in 17 lumbosacral spinal nerve roots (23%) in patients with spinal stenosis.
Neural Regeneration Research, 2017 • May 1, 2017
Following SCI, the musculoskeletal system undergoes changes, including loss of muscle size and strength, leading to reduced bone mineral density and other health issues. Analyzing the cross-sectional ...
KEY FINDING: MRI is an effective method for analyzing lower leg muscles in SCI patients, providing detailed information about muscle volume, architecture, and composition.
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.
J Extracell Vesicles, 2022 • November 7, 2022
This research introduces EVAnalyzer, a new open-source plugin for Fiji designed for automated single vesicle quantification from fluorescence microscopy images. The study establishes a robust procedur...
KEY FINDING: EVAnalyzer enables the automated and quantitative analysis of single vesicles from imaging data, using a robust protocol for capture, labeling, and fluorescent imaging of EVs.
J Korean Med Sci, 2006 • January 1, 2006
This retrospective study analyzed abdominal ultrasound results of 500 SCI patients to identify abdominal organ abnormalities. The study found a high incidence of abnormalities, including liver, bladde...
KEY FINDING: Abnormal sonographic findings were observed in 45.2% of the 500 patients.
Journal of Translational Medicine, 2013 • December 20, 2013
The study compared CT-guided stem cell transplantation with open surgical transplantation for treating spinal cord injury sequelae, finding CT-guided transplantation to be safer and more effective. Cl...
KEY FINDING: CT-guided stem cell transplantation resulted in better clinical outcomes compared to open surgical transplantation and the control group.
Journal of Biomedical Optics, 2024 • March 19, 2024
This paper introduces the photoacoustic differential attenuation spectrum (PA-DAS) method to study the attenuation characteristics of cancellous bone for osteoporosis diagnosis. The method modifies Bi...
KEY FINDING: The photoacoustic differential attenuation spectrum (PA-DAS) method can effectively differentiate osteoporotic bone from healthy bone.
J Orthop Res, 2018 • January 1, 2018
This study demonstrates the feasibility of using NIRS to detect changes in hemoglobin concentration in the human cortical bone. The study found that in able-bodied individuals, total blood content in ...
KEY FINDING: In able-bodied individuals, deoxygenated blood increased in the tibia during and after rowing exercise.
