MRT von Sprunggelenk und Fuß: Varianten und Pitfalls

An Sprunggelenk und Fuß können die teils komplexen anatomischen Strukturen mit der MRT sehr genau beurteilt werden. Technische Faktoren und anatomische Normvarianten können diese Beurteilung jedoch erschweren. In diesem Beitrag wird der Umgang mit solchen Schwierigkeiten vorgestellt.

Kernaussagen

• Die Anatomie der Sprunggelenke und Füße kann in vielen Fällen eine Herausforderung darstellen, wenn es gilt, einen normalen Zustand von Varianten zu differenzieren.

• Um Fehldiagnosen zu vermeiden, ist ein entsprechendes Wissen über die normale Anatomie und ihre Varianten genauso notwendig wie die Kenntnis potenzieller technischer Pitfalls.

• Für eine korrekte Interpretation von MR-Befunden sind somit grundlegende Kenntnisse über das Spektrum von Varianten erforderlich, die im Normalfall keine klinische Signifikanz aufweisen, im Einzelfall aber auch zu Beschwerden beitragen können.
