• DTI and tractography support conventional MR neurography in the detection of UNE • Regionally reduced FA values and discontinuous tractography patterns indicate UNE • T2-weighted MR neurography remains the imaging gold standard in cases of UNE • DTI-based ulnar nerve tractography offers additional topographic information in 3D.
• DTI-based neurography detects nerve changes during acute nerve compression. • Compression leads to a transient increase in local radial nerve FA values. • DTI provides insights into radial nerve vulnerability at the spiral groove.
Lange Zeit genügten zur Beurteilung der Bandscheiben die 2 Begriffe Protrusion und Prolaps: ▪ Eine Protrusion der Bandscheibe stand für die breitbasige Vorwölbung der Bandscheibe, die konservativ zu behandeln war. ▪ Der Prolaps oder Vorfall der Bandscheibe stand für eine umschriebene dorsalseitige Vorwölbung der Bandscheibe, die bei entsprechender Klinik auch chirurgisch behandelt werden konnte.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
