To prospectively evaluate the nerve regeneration after traumatic nerve transsection using diffusion tensor magnetic resonance imaging (DTI MR imaging).
Observational Model: Cohort, Time Perspective: Prospective
University of Zurich
At Beckman Laser Institute, University of California, Irvine, the investigators have developed diagnostic device call 'optical coherence tomography (OCT).' The imaging technique used in cl...
This two tiered study is a multi-center, open label, surveillance study of the use of continuous nerve blocks with the ON-Q® C-bloc and either nerve stimulator or ultrasound guided contin...
Cholinergic neurons in the basal forebrain project widely to the cerebral cortex and hippocampus. These neurons depend on nerve growth factor (NGF) from their target areas for survival. Im...
Sciatic nerve blocks are frequently used for anesthesia or analgesia for surgery of the lower legs. Currently, if ultrasound is used to find the sciatic nerve, the leg must be raised to l...
The purpose of this study is to analyse the ability to selectively block the posterior tibial nerve sparing the function of the common peritoneal nerve. To assess the efficacy of blocking...
Diagnostic imaging techniques play an important role in assessing the exact location, cause, and extent of a nerve lesion, thus allowing clinicians to diagnose and manage more effectively a variety of...
To investigate changes of inner retinal layers and optic nerve head (ONH) in patients with dry age-related macular degeneration (AMD) and demonstrate the pattern of these changes.
The p62, also called sequestosome 1 (SQSTM1), plays a crucial role in tumor necrosis factor (TNF)-induced optic nerve degeneration. Brimonidine has been shown to have protective effects on retinal gan...
Taste system is a perfect system to study degeneration and regeneration after nerve injury because the taste system is highly plastic and the regeneraton is robust. Besides, degeneration and regenerat...
To quantitatively evaluate nerve roots by measuring fractional anisotropy (FA) values in healthy volunteers and sciatica patients, visualize nerve roots by tractography, and compare the diagnostic eff...
Loss of functional activity and trophic degeneration of nerve axons and their terminal arborizations following the destruction of their cells of origin or interruption of their continuity with these cells. The pathology is characteristic of neurodegenerative diseases. Often the process of nerve degeneration is studied in research on neuroanatomical localization and correlation of the neurophysiology of neural pathways.
The use of molecularly targeted imaging probes to localize and/or monitor biochemical and cellular processes via various imaging modalities that include RADIONUCLIDE IMAGING; ULTRASONOGRAPHY; MAGNETIC RESONANCE IMAGING; fluorescence imaging; and MICROSCOPY.
Degeneration of distal aspects of a nerve axon following injury to the cell body or proximal portion of the axon. The process is characterized by fragmentation of the axon and its MYELIN SHEATH.
A technetium imaging agent used in renal scintigraphy, computed tomography, lung ventilation imaging, gastrointestinal scintigraphy, and many other procedures which employ radionuclide imaging agents.
Optical imaging techniques used for recording patterns of electrical activity in tissues by monitoring transmembrane potentials via FLUORESCENCE imaging with voltage-sensitive fluorescent dyes.
