7 Tesla MR Imaging: Opportunities and Challenges

Abstract

The urge to increase magnetic field strength is driven by a number of potentially beneficial physical changes, possibly resulting in improved MR diagnostics. With the successful introduction of in-vivo ultra-high-field MR imaging, by means of 7 Tesla MRI, the focus of scientific research has been set on compiling different applications of brain and body imaging. This review presents an overview on the current status of 7 T MR imaging, investigating the opportunities as well as challenges associated with ultra-high-field MRI.

Zusammenfassung

Die Steigerung der Magnetfeldstärke geht mit einer Reihe von potenziell vorteilhaften physikalischen Veränderungen einher, die zu einer verbesserten Diagnostik von Erkrankungen führen können. Mit der erfolgreichen Einführung der in vivo 7 Tesla Magnetresonanztomografie wurde der wissenschaftliche Fokus auf die Etablierung verschiedener neuro- und allgemeinradiologischer Anwendungsfelder gelegt. Diese Übersichtsarbeit gibt einen Überblick über den aktuellen Stand der 7 Tesla MRT, verbunden mit dem Ziel die Möglichkeiten und Grenzen der Ultrahochfeldbildgebung aufzuzeigen.
