[Insight-users] Cannot change the series description (0008|103E) of a dicom file using ITK

[andreasfm at web.de]

Dear ITK users!

I want to change the header of a dicom file. It works fine with all but one dicom tag. I cannot change the series description (0008|103E).
My code below is adapted from DicomImageReadChangeHeaderWrite.
Does anyone know why
    itk::EncapsulateMetaData<string>( dictionary, "0008|103E", "a new series description, THIS DOES NOT WORK" );
is not working, i.e. after saving the dicom file the tags has not changed?
Thanks,
Andreas
