of image intensities. Unlike in other modalities such as x-ray 
computerized tomography, MR images taken for the same patient on 
the same scanner at different times may appear different from 
each other due to a variety of scanner-dependent variations, and 
therefore, the absolute intensity values do not have a fixed 
meaning. We have devised a two-step method wherein all images 
can be transformed in such a way that for the same protocol and 
body region, in the transformed images similar intensities will 
have similar tissue meaning. Standardized images can be 
displayed with fixed windows without the need of per case 
adjustment. More importantly, extraction of quantitative 
information with fixed windows without the need of per case 
adjustment. More importantly, extraction of quantitative 
information about healthy organs or about abnormalities can be 
considerably simplified. This paper introduces and compares new 
variants of this standardizing method that can help to overcome 
some of the problems with the original method.
