I am still having trouble with this unfortunately.
However, it appears that on my original stack, these numbers appear to be calibrated by the DICOM header. Highlighted in red is the calibrated HU value and in brackets, what I assume is the raw pixel value? How can I find out how the raw pixel value is scaled?

I have looked online, and apparently the typical HU calibration function is:
hu = pixel_value * slope + intercept
But this wouldn't work in this context? It would give:
Pixel value= 1
Intercept = -1024
HU= 32994*1 - 1024 = 31970 HU
It should be 226 HU. Any idea how I can find out how the number in brackets is scaled, please?
