This year MRI celebrates the 50th anniversary of P. Lauterbur’s seminal discovery paper on MR imaging published on March 16, 1973. The first human sized scanners producing ‘proof of principle’-images were based on homemade magnets with a typical field strength of ~ 0.05 Tesla. First commercial MRI machines appeared in the early 80s with field strength approaching 0.5 Tesla. Sounds familiar? Today MRI at 0.05 and at 5.0 Tesla are both as ‘hot topics’ in the current developments. Although MRI has been around for 50 years, there are still intense new developments driven by the need to improve the performance in the closely interwoven performance parameters SNR, spatial, and temporal resolution. Some buzzwords for the current intense technological and methodological developments are compressed sensing, sparse sampling, ultra- low and high field MR, 13C-hyperpolarization, new concepts for spatial encoding (Inverse Imaging (InI), OVOC(MREG), PatLoc,…) and others. The presentation will present the ‘then and now’ of MRI and discuss opportunities from ongoing MRI innovations to demonstrate how ultra-low and ultra-high MRI open up new ways into the future of MRI.
