Zusammenfassung

Das Ziel einer MRT des Abdomens ist eine im Vergleich zu Sonographie und Computertomographie bessere Darstellung krankhafter Befunde sowie eine genauere artdiagnostische Aussage (z.B. die Differenzierung zwischen Leberhämangiom und Lebermetastase). Dieses Ziel zu erreichen, ist im Vergleich zu MR Untersuchungen des Kopfes, des Spinalkanals oder des Haltungs- und Bewegungsapparats weitaus schwieriger, da sich bei MR-Untersuchungen des Abdomens zahlreiche untersuchungstechnische Probleme (z.B. Bewegungsartefakte) stellen. Hinzu kommt, daß einer der wesentlichen Vorteile der MRT — die freie Wahl der Schichtebene — für die meisten Fragestellungen im Abdomen von untergeordneter Bedeutung ist. Der Untersucher muß sich somit auf die Ausnutzung des hohen Weichteilkontrasts konzentrieren. Gleichzeitig eine gute räumliche Auflösung zu erreichen, ist die Grundvoraussetzung, um mit den etablierten bildgebenden Verfahren konkurrieren zu können.
