Hello,

I have segmentations from PET dicom source images that I would like to export as DICOM-RT files. I have the extension SlicerRT. Is this possible?

I very recently [added](https://github.com/Slicer/Slicer/pull/8538) PET export to the CreateDicomSeries module, and I think that would fix this issue. Please download the latest preview version and try with that.
