a) MS Paint does not handle 16 bit images
b) copy an image via clip board will instert the image
   into the *FrontEnd* but not into the Kernel. You can see
   this image but you can't do anything with it. 
   Just looking on a 16 bit image is nonsense because
   the human eye can nonly see 150 -- 200 gray scales
c) Import[] with 16 bit TIFF's scale down the range to 8 bit

16 bit (more precise 12 bit) are the standard bit depth
of all most all medical imagine software and a conversion
of the images to DICOM format may also a way to read the
16 bit images into the kernel.
