Sorry I've misinterpreted the "Display range: -654 - 1846" which means
-654 to +1845 Hounsfield units and which is *perfectly OK*.
I think you can work with such images when imported to ImageJ!
Just keep in mind that the gray-values are scaled in Hounsfield units.
Good luck (and sorry for the confusion)
Herbie
