Which DICOM tag contains MRI DWI b-values?

Does anyone know which DICOM tag contains b-values for a GE MRI DWI sequence? Is it the same for Siemens and Philips data too?

For GE, I recently found b-values stored in (0043,1039) for data acquired on a Signa PETMR (MP26 software).

@RuiPedroTeixeira do you know from your diffusion work with Siemens scanners if they use the same tag for b-values?

As far as Iā€™m aware for non XA systems the b-value is stored in (0019,100c) :slight_smile:

I just came across the site below, seems to have b-value and diffusion vector DICOM tag details for a number of manufacturers.
