Zusammenfassung

Die Magnetresonanztomographie (MRT) ist ein in der klinischen Routine etabliertes bildgebendes Verfahren, das auf den Prinzipien der Kernspinresonanz (Magnetresonanz) basiert und Schnittbilder des Körpers erzeugt. In diesem Kapitel werden die Grundprinzipien sowie die physikalisch-technischen Grundlagen der Komponenten eines MRT. Bei den Komponenten wird die Rolle der Magnetfeldstärke eines supraleitenden oder Permanentmagneten angesprochen, die Bedeutung eines leistungsfähigen Magnetfeldgradientensystems zur räumlichen Zuordnung und die Kombination von Sende- und Empfangsspulen zur Optimierung von Bildqualität und Messzeit. Zum Verständnis der Grundlagen sind nachfolgend die wichtigsten gewebespezifischen Parameter vorgestellt, die für einen potenziellen Bildkontrast verantwortlich sind. Obwohl die MRT eine extrem sichere Bildgebungsmodalität darstellt, so gibt es doch einige bekannte Gefahrenpunkte für Bedienpersonal und Patient, die zu beachten sind und denen ein eigener Abschnitt gewidmet ist.
