Hi Robert,
looking forward to the whole dcm set of files, i find out that the field "0043,0000" seems unique for the single B_X set of images. So i tried to se the AddSeriesRestriction to "0043|0000" but it seems no to work... why?
Thanks,
Ale

However, even if it is not the best solution, I would distinguish the files using windowing parameters. A window width (0028,1051) of about 4000 suggests that the second file is an ADC map. Can you tell us, who the vendor of your scanner is? Or where are these DICOM files from?
