Thanks for the response, George and John. MI won't open the image in either raster or running georeg.mbx - I had already tried that. When I just try to open as a raster, I get "Raster engine unable to recognize image file format". When I try to open using georeg.mbx, I get "Specified file does not contain valid registration information." The vendor that distributed these yesterday at the meeting I attended said because they are 11 bit, in ArcView they would have to be viewed with ArcView Image Extension, but I don't know what I would need with MI. Will keep trying.
