OK.
Probablely the name 'Load'  confused you.
The method load the *header*, not the image pixels.
Just add
fh->GetImageDataRaw();
to load the pixels.
(using
fh->GetImageData(); would convert any image with a LUT into an RGB image.
For 'gray level images', GetImageData() and GetImageDataRaw() are 
equivalent)

By the way, did you solve your compile time ITK problem?


Just tell me : you dowloaded gdcm (version 1.3.1) and you work with a 
standard version of ITK, right?
ITK uses dgcm1.2.x,  nad prbabely, this confuses the complier.
Actually, I don't know waht you wanted to do is possible?
Mathieu, any comment?
(maybe you told Clemens to convert his data into Raw images?)
