Nerve Fascicles and Epineurium Volume Segmentation of Peripheral Nerve Using Magnetic Resonance Micro-Neurography

open access: yesAcademic Radiology, 2016
Rationale and Objectives The aims of this study were to propose a semiautomated technique to segment and measure the volume of different nerve components of the tibial nerve, such as the nerve fascicles and the epineurium, based on magnetic resonance ...

Gradient-Based Edge Detection With Skeletonization (GES) Segmentation for Magnetic Resonance Optic Nerve Images

open access: yesBiomedical Signal Processing and Control, 2023
This study proposes a new segmentation method called gradient-based edge detection with skeletonization (GES) for the cross-sectional optic nerve on magnetic resonance (MR) images acquired with T1-weighted fast spoiled gradient-echo (FSPGR) without fat ...

Segmental Neurofibromatosis of the Sciatic Nerve

Neurosurgery, 1992
A case of rare segmental neurofibromatosis is presented. Multiple neurofibromas along the right sciatic nerve were found. Other typical manifestations of neurofibromatosis were absent. By microsurgical dissection, it was possible to remove the neurofibromas from the nerve trunks and to preserve all motor and sensory functions.

Stimulation of Peripheral Nerve Regeneration by an Isolated Nerve Segment

Annals of Plastic Surgery, 1986
An experimental model in rats was used to assess the stimulant effect of an isolated nerve segment on peripheral nerve regeneration. In a first group of animals, 14 mm of the femoral nerve was removed unilaterally and the gap was bridged with femoral vein taken from the other side.

Automatic Segmentation of Optic Nerve Fibers

2008 International Conference on BioMedical Engineering and Informatics, 2008
The cross-sectional morphometry of different fiber types is an important tool in studying the structure and function of healthy and diseased human optic nerve. However, such studies are hampered by the thousands of fibers involved when manual segmentation has to be used.
