Edelstein moved to Scotland, where he had two three-year postdoctoral research fellowships: the first at the
University of Glasgow, where he worked on gravitational wave detection from 1974 to 1977, and the second at the
University of Aberdeen from 1977 to 1980, where he was part of the group that performed the first full-body human MRI scan. Edelstein worked for the
General Electric Research and Development Centre in Schenectady from 1980 to 2001, where he continued to work in a group which included colleague Paul Bottomley on the development of GE's MRI technology. He was named a Coolidge Fellow, the highest corporate scientific honor bestowed by GE R&D, and won the GE Dushman Award for “Outstanding Technical Work on Nuclear Magnetic Resonance, Imaging and Spectroscopy." After 21 years at GE, he founded MRScience LLC, through which he continued to work on the technology. He also served as a visiting scientist at
Rensselaer Polytechnic Institute in New York and a senior research associate at
Case Western Reserve University in Ohio. Edelstein became a Visiting Distinguished Professor of Radiology at
Johns Hopkins University in 2007. During his career, he held 49 patents. ==Recognition==
