Zusammenfassung
Purpose: 7.0 Tesla ultra high field systems are currently introduced for clinical imaging, especially focusing on high resolution structural imaging and fMRI applications. Single-shot EPI at 7.0 Tesla will suffer from severe distortions, while multi-shot techniques can often not establish the required temporal resolution. Furthermore, a shorter TE will be required at this high field strength which is often not possible with a single-shot approach. We investigated the use of a multi-shot technique with echo-shifting (PRESTO) to overcome some of the distortions and to prevent low temporal resolution. The aim of th…
