G'day,
Unfortunately, Mathematica Export writes out an 8-bit image and its own 
represenatation based on Raster, complete with axes etc. And there are 
numerous elements contained in a DICOM file to acurately represent the 
collected image. Mathematica Export does however contain ConversionOptions 
for DICOM export, but without knowing the DICOM standard they are of 
little use.
For the specific question raised by Danny, one would have to write out a 
file with Export["filename", imageData, "Integer16"], or better yet, write 
out the processed data to a file with BinaryWrite and Append to it a line 
that follows the header guidelines as defined by the DICOM standard. I 
guess the short answer to the original post is, "Yes it can be done, but 
you would have to roll out your own DICOM export routine to accurately 
represent the data as expected in medical imaging".
Cheers
Yas
