Read the sections from the DICOM image, then SUV can be computed from the equation.
(0008,0032) [100209.015000] # AcquisitionTime
(0010,1030) [75] # PatientsWeight (kg)
(0018,1072) [090000.000000] # RadiopharmaceuticalStartTime
(0018,1074) [360100006.10352] # RadionuclideTotalDose (Bq)
(0018,1075) [6586.2] # RadionuclideHalfLife (seconds)
(0028,1052) [0] # RescaleIntercept
(0028,1053) [2.3295469284058] # RescaleSlope
Given X for a pixel value, Y= (RescaleIntercept + RescaleSlope X) exp(ln2*(AcqusitionTime- RadiopharmaceuticalStartTime)/ RadionuclideHalfLife)
SUV = Y/( RadionuclideTotalDose/ PatientsWeight)
