I have a dicom file taken from a GE Advance PET/CT scanner and one of the fields present is the RadionuclideTotalDose indicating how much activity the patient was given.
However, dicominfo does not return this field. Further, dicomdump (Jeff Mather) lists the field in the screen dump but it doesn't appear to be present in the "attrs" structure returned by the dicomparse mex function when I search through this structure looking for the specific Location where I know this header tag should be.

Well, this is surprising to me, since all of the DICOM functions in the Image Processing Toolbox use the same parser as dicomdump. If you see it appear in dicomdump it should show up in dicominfo. Is it possible that the attribute is hiding inside a structure, perhaps in the "RadiopharmaceuticalInformationSequence"?

If that doesn't solve the issue, would it be possible for you to send me one of the files that exhibits this behavior? Feel free to e-mail directly.

Jeff,
You're a life saver - it WAS hidden in the RadiopharmaceuticalInformationSequence structure. I had noticed that the location information from dicomdump was missing all of the tags related to all of the Radiopharmaceutical information but never pieced together that they could ALL be under one tag.
Many thanks,
Ross
