Operating beyond 3T: Is clinical use in reach?
VIENNA - The standard field strength of clinical MR units is still 1.5 tesla, but the past five years have seen a tremendous increase in the number of devices operating at 3.0 tesla. In addition, whole-body systems up to 9.4 tesla have become available in experimental settings and have already proved to be significantly beneficial in special purpose examinations.
