MR-Neurografie – eine Einführung

Diese Arbeit stellt die MR-Neurografie mit ihrer Technik, den benötigten MR-Protokollen und einer strukturierten Befundung vor. Normalbefunde und pathologische Veränderungen werden systematisch gegenübergestellt. Fortgeschrittene Bildgebungstechniken wie die – noch nicht als klinischer Standard etablierte – Diffusionsbildgebung, speziell die Diffusionstensorbildgebung, werden ebenfalls kurz erklärt.

Kernaussagen

• Die MR-Neurografie ist eine hervorragende Methode zur Darstellung peripherer Nerven und ihrer Veränderungen.

• In der klinischen Routine kommen klassische T2w Sequenzen zum Einsatz, ergänzt durch optimierte 3-D-Sequenzen für die Darstellung peripherer Nerven.

• Die Gabe von Kontrastmittel und der Einsatz von DWI und DTI ist bei bestimmten Indikationen sinnvoll.

• Die Bildgebung sollte, wie die Befundberichte, standardisiert werden.

• Eine enge Abstimmung mit den klinischen Kollegen über Indikationen und Befundinterpretationen ist hilfreich und gewinnbringend.
