The German Ultrahigh Field Imaging network (GUFI, www.mr-gufi.de) is a user group of 13 German and neighboring sites that all operate a UHF (7T or 9.4T) MRI system. Due to the lack of common quality assurance (QA) procedures for UHF, GUFI started an initiative to unify QA procedures at these sites. A QA phantom and measurement protocol were developed especially for UHF that is currently being rolled out to all member sites. The QA data allow monitoring of individual system performance based on long-term data analysis or by comparison to pooled data from all sites.
