Canada's largest magnet finds home in new MRI program in London [correction] CMAJ 1997;156:637 Because of incorrect information supplied to the author, this article by Michael OReilly (CMAJ 1997;156:69-70) contained some errors. Dr. Seiji Ogawa, whose surname was misspelled, developed the principles behind functional MRI (fMRI) at AT&T Bell Laboratories, and then worked with Dr. Kamil Ugurbil's MRI research group at the University of Minnesota to produce one of the seminal papers demonstrating fMRI in humans. Although Dr. Ravi Menon was involved in the project as a postdoctoral fellow, he did not codevelop the technique. As well, the system was built by Siemens Medical Systems, but in conjunction with Varian NMR Instruments. We apologize for these errors. -- Ed. | CMAJ March 1, 1997 (vol 156, no 5) / JAMC le 1er mars 1997 (vol 156, no 5) | / >
