Zusammenfassung
Mit dem Einsatz der Ganzkörper-MRT jenseits der 1,5 Tesla (T) erleben spektroskopische Verfahren (MRS) eine Renaissance. Das überlegene Signal-zu-Rausch-Verhalten klinischer 3-T-Tomographen erlaubt die zuverlässige Akquisition von MR-Spektren nicht nur in fixierten Organen, sondern auch in atembewegten Zielen wie der Leber. Im Folgenden werden die Prinzipien der 1H-MRS und erste eigene Erfahrungen bei Leber- und Lebermalignomspektroskopie an einem 3-T-Ganzkörper-MRT beschrieben.
Abstract
Use of whole-body MRI beyond 1.5 Tesla (T) has initiated a renaissance in spectroscopic procedures (MRS). The superior signal-to-noise ratio of clinical 3T tomographs allows reliable acquisition of MR spectra not only in fixed organs but also in targets moved by breathing such as the liver. The following contribution describes the principles of 1H MRS and our own initial experiences with spectroscopy of the liver and hepatic malignant tumors with 3T whole-body MRI.
