Hi everyone can help me? I have image (PET) in format dicom 256×256 dimension. then the min pixel is 0 and the max pixel is 32657. Actually, what is the no meaning? 1) is it means the dose? 2) or intensity of the beam or radiation? 3) and what is the unit of that pixel no?

You need to access one of the dicom headers to find out what the numbers represent. See http://dicom.nema.org/medical/Dicom/2016b/output/chtml/part03/sect_C.8.9.html
