depends on what you call 'header' (no such thing in DICOM standard
AFAIK). itk::GDCMImageIO implement the public interface of the
ImageIO, so you only need to execute the information part
'ExecuteInformation', the Pixel Data element will not be loaded.

I do not understand 'edit in place'.
Everything is copied from the DICOM header into the itk::MetaDataDict.
then you can edit the MetaDataDict, but I do not know if this fits
your definition of 'in place'.

If you are looking for DICOM only operation, you should maybe consider
using directly gdcm (and/or dcmtk ?).
