[Insight-users] Modality LUT transform with gdcmIO

[Mathieu Malaterre]

Jesús,

	No ITK will always apply the modality LUT for grayscale image. You 
cannot control this option. There is IMHO no reason to disable this 
behavior. Please describe why you are looking for something like this 
This is potentially dangerous, since it will affect professional 
interpretation of the image.
