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
