I am not sure about the slice acquisition order of some EPI sequences from a GE Architect Signal 3T scanner. Does anybody know if there is a way to extract this information from the dicom files (eg, through dicom_hdr)? I tried but I couldn’t find any of the tags that were suggested on the web as potentially carrying that information. I do know that the sequence was interleaved, but I don’t know whether is alt+z or alt+z2, for instance. To add further complication, some (but not all) of the data have been acquired with parallel imaging (“hyperband” in GE speak).
thanks in advance for any suggestion
