You may need something like `writer->SetMetaDataDictionary(reader->GetMetaDataDictionary());`. Maybe look at this [DicomSeriesReadSeriesWrite example](https://github.com/InsightSoftwareConsortium/ITK/blob/master/Examples/IO/DicomSeriesReadSeriesWrite.cxx#L277-L293).
Also it is desirable to use backticks for [code formatting](https://discourse.stonehearth.net/t/discourse-guide-code-formatting/30587).

I found the “Study Instance UID” and “Series Instance UID” has changed!
But I don’t know why?

Hello @wulicheng,
This is actually a good thing. You processed the images and when you save them they should be to a different series, likely with the same study number.
If you still feel you want to retain the study and series numbers you will need to explicitly set the writer to use GDCMImageIO, set the series/study number to what you want in the meta-data dictionary and then configure the GDCMImageIO to use these by calling the [KeepOriginalUIDOn](https://itk.org/Doxygen/html/classitk_1_1GDCMImageIO.html#ae215297a5be5792d5119940aca174514) method.

Hi @mihail.isakov,
Good catch, didn’t even notice that when pointing to the doxygen.
Looks like something is wrong with the doxygen generation as the [documentation in the code](https://github.com/InsightSoftwareConsortium/ITK/blob/75149ceee513ea0b3b43547af19ce250b4991646/Modules/IO/GDCM/include/itkGDCMImageIO.h#L182) is correct.
@dzenanz, any idea what’s wrong with doxygen generation?
