SUV caculate

I viewed PET images using your nice software and I get SUVbw in ellipse tools. This show some information about that. It includes SUV value. I see your answer under the "How is SUV calculated from DICOM PET/CT image files" theme how to calculate the SUV.
But I used the formula below to get the SUV value the same as shown on the software. This formula is SV * ResacleSlope + RescaleIntercept. The SV is the value stored in (7FE0,0010). ResacleSlope is the value stored in (0028,1053). RescaleIntercept is the value stored in (0028,1052).
But I tried your formula with my PET data. My calculated result is not the same as Radiant reported.

Thank you!

PET DICOMs can have pixel data with different units (tag 0054,1001). The formula in https://www.radiantviewer.com/dicom-viewer-forum/how-is-suv-calculated-from-dicom-pet-ct-image-files/946/ can be used for pixel data with Bq/ml values.
