Retrospective. Primary: to assess if axial damage ratios are predictors of future walking after spinal cord injury (SCI), and if they add any predictive value if initial neurological impairment grades are available. Secondary: to determine if lateral spi
Spinal cord stimulation for axial low back pain: A prospective controlled trial comparing 16-contact insulated electrodes with 4-contact percutaneous electrodes. Neuromodulation. 2006; 9 (1):56–67.North R, Kidd D, Olin J, Sieracki F, Petrucci L. Spinal cord stimulation for axial low back ...
Spinal cord, major nerve tract of vertebrates, extending from the base of the brain through the canal of the spinal column. It is composed of nerve fibres that mediate reflex actions and that transmit impulses to and from the brain. The spinal cord and t
The 碌-MRI scans were performed on a 9.4 T vertical-bore NMR microimaging system: anAvance DMX400 (Bruker-Biospin, Inc.) with Micro2.5 tri-axial gradients (100 G/cm peak) and BAFPA40A. C. WrightG. ZhangS. L. WehrliM. E. Selzer...
but other known causes include lymphoma and leukemia metastasis. MRI is by far the most sensitive imaging modality for detection and reveals a round or ovoid intramedullary nodule that is isointense to spinal cord and surrounded by cord edema (hyperintense on T2WIs, and hypointense on T1WIs), ...
Cerebral strokes can disrupt descending commands from motor cortical areas to the spinal cord, which can result in permanent motor deficits of the arm and hand. However, below the lesion, the spinal circuits that control movement remain intact and could be targeted by neurotechnologies to restore ...
MRI, magnetic resonance imaging Figure 2: Axial MRI of the spine. (A) T1-weighted axial MRI shows an extramedullary tumor on the left side of the spinal cord causing compression and displacement to the right. (B) T2-weighted axial MRI shows an extramedullary tumor with enhancement of parave...
However, no software package exists to process mpMRI data of the spinal cord. Despite the numerous clinical needs for such advanced mpMRI protocols (multiple sclerosis, spinal cord injury, cervical spondylotic myelopathy, etc.), researchers have been developing specific tools that, while necessary, ...
MRI: T2-WI hyperintensity extends from T11 to the conus medullaris involving the central gray matter with cord swelling (a–c). Note the abrupt termination of the AKA (arrow) on subsequent DSA suggesting an embolic occlusion (d) (Courtesy Dr. Kim Nelson and Tibor Becske, NYU Medical Center...
Spinal cord compression in beta-thalassemia SA Salehi et al 118 Figure 1 (a) Sagittal MRI of the thoracic spine showing the spinal cord compression (white arrow). (b) Axial MRI of the mid- thoracic level demonstrating the amount of cord displacement by the extramedullary mass (white arrow)....
