MR Neurography: Advances
High resolution and high field magnetic resonance neurography (MR neurography, MRN) is shown to have excellent anatomic capability. There have been considerable advances in the technology in the last few years leading to various feasibility studies using different structural and functional imaging approaches in both clinical and research settings. This paper is intended to be a useful seminar f...
متن کاملMR Neurography - Imaging Peripheral Nerves
MR imaging of peripheral nerves not only allows sensitive detection of peripheral nerve abnormalities but also displays high detail of regional anatomy and improves specificity of diagnosis. The use of MR imaging for diagnosis and evaluation of peripheral nervous system disorders was initially reported in the late 1980’s. Since then, expertise gained through experience over the last decade coup...
متن کاملMagic angle effects in MR neurography.
BACKGROUND AND PURPOSE Magic angle effects are well recognized in MR imaging of tendons and ligaments, but have received virtually no attention in MR neurography. We investigated the hypothesis that signal intensity from peripheral nerves is increased when the nerve's orientation to the constant magnetic induction field (B(0)) approaches 55 degrees (the magic angle). METHODS Ten volunteers we...
متن کاملMR neurography in intraosseous median nerve entrapment
Intraosseous entrapment of the median nerve is an uncommon complication of elbow dislocation and fractures. The condition is seen to occur in adolescent age group with a remote history of trauma. We report two rare cases of type 2 intraosseous median nerve entrapment. Though the diagnosis of median neuropathy is made with clinical tests and neurophysiological studies, however exact site of entr...
متن کاملMR neurography of a vagal neuropathy.
A 46-year-old man with a history of recurrent facial nerve palsies, right trigeminal neuralgia, and Horner syndrome presented with subacute onset of right laryngeal hemiparesis. CSF analysis revealed normal cell count and elevated protein level with albumin-cytologic dissociation. Imaging workup ruled out compressive and infiltrative causes. Magnetic resonance neurography (figures 1A and 2, A–D...
