MR-Neurografie – Bildgebung des peripheren Nervensystems

Die Magnetresonanzneurografie (MRN) ist ein nicht invasives Untersuchungsverfahren mittels hochauflösender Magnetresonanztomografie (MRT) zur präzisen Diagnostik von Pathologien des peripheren Nervensystems und deren zugrunde liegenden Ätiologien. Bereits jetzt wird die anatomische MRN auf breiter Basis zur Diagnostik einer Vielzahl von Erkrankungen des Nervensystems verwendet. Ebenso sind Verlaufskontrollen von Degenerations- und Regenerationsprozessen möglich. Dieser Artikel stellt neue, sowohl derzeit bereits verwendete als auch in Entwicklung stehende MRN-Technologien sowie deren klinische Anwendung und zukünftiges Potenzial als nicht invasive Methoden zur Abklärung von Störungen des peripheren Nervensystems vor.

Abstract

Magnetic resonance neurography (MRN) is a non-invasive technique using magnetic resonance imaging (MRI) in order to diagnose peripheral nerve pathologies and their underlying etiologies. MRN is already in clinical use and is now mostly used to delineate the anatomy of nerves and to establish the continuity or discontinuity of nerves in patients with traumatic nerve injuries, as well as to monitor processes of peripheral nerve degeneration and regeneration. This article reviews established and evolving novel MRN technologies with regard to their potential to meet the requirements for non-invasive imaging of peripheral nerves in clinical settings.
