Hum...
I have never seen this happen with CT images (due to the nature of
Houndsfield Units this is not typical to go beyond 16 bits well at
least for human composition, in which case a single rescale
slope/intercept should be enough).
Do you have by any chance a sample dataset, or do you recall the
private vendor doing this ?
