Zusammenfassung
Die Magnetresonanztomographie (MRT) der Leber ist in der radiologischen Diagnostik fokaler und diffuser Lebererkrankungen fest etabliert und untersteht einem steten Wandel durch den fortwährenden technischen Fortschritt. Durch Neuerungen bei der Hardware, den Sequenzen und der Bildnachverarbeitung konnten in den letzten Jahren deutliche Fortschritte erzielt werden. Insbesondere auf dem Gebiet der Untersuchungssequenzen kam es zu Entwicklungen, die das diagnostische Spektrum der MRT erweiterten, zu einer Verkürzung der Scanzeit führten und zu einer Verbesserung der Bildqualität beitrugen.
Gegenstand dieses Artikels ist es, den technischen Hintergrund und die klinische Anwendung neuerer Sequenztechniken zu erklären und so die Möglichkeiten und den Umfang eines modernen MRT-Untersuchungsprotokolls für die Leber darzustellen.
Abstract
Magnetic resonance imaging (MRI) of the liver has become an essential tool in the radiological diagnostics of both focal and diffuse diseases of the liver and is subject to constant change due to technological progress. Recently, important improvements could be achieved by innovations regarding MR hardware, sequences and postprocessing methods. The diagnostic spectrum of MRI could be broadened particularly due to new examination sequences, while at the same time scanning time could be shortened and image quality has been improved. The aim of this article is to explain both the technological background and the clinical application of recent MR sequence developments and to present the scope of a modern MRI protocol for the liver.
