Increasing strength of the static magnetic field is the main trend in modern human magnetic resonance imaging (MRI). Performing MRI in ultrahigh fields (7 T or more) involves many effects both enhancing and deteriorating the image quality, and some effects previously unobservable in weaker fields. We review the main impacts of using ultrahigh fields in human MRI, including new challenges and the solutions proposed. We also discuss new magnetic-resonance scan methods that were unavailable with lower field strength (below 7 T).
