From the achieved progress regarding all aspects of MRI technology, an MR scan at 1.5 T in the mid 1980s has very little in common with the equivalent scan in 2020. Yet, many reasons bring low field MRI in a situation quite different from 40 years ago. The promise of rapid exams or higher image resolution within a reasonable time won over other considerations and set the standards for MR value. At the time, the inherent gain in sensitivity of high field, which would translate in more signal per unit time, quickly ended this debate. In its first 10 years of existence, there was an open debate on the question of most relevant MRI field strengths considering the gain in T 1 contrast, simpler cooling strategies, lower predisposition to generating image artifacts, and naturally cost reduction of small footprint low field systems. Center for Adaptable MRI Technology, Department of Biomedical Engineering, University of Basel, Allschwil, Switzerlandįor about 30 years, MRI set cruising speed at 1.5 T of magnetic field, with a gentle transition toward 3 T systems.
