When I load my dicom series into 3Dslicer the z order is shuffled, meaning that the slice location values are probably incorrect. however if I use other software to load them in order by the dicom file names, they are properly ordered. is there a way to get 3Dslicer to order slices based on their file names?

Thanks,

Filenames must be ignored when a volume is reconstructed from frames stored in DICOM file format. The only information that matters is the image position and orientation tags.

Do you have any problems when you [load the image using the DICOM module](https://slicer.readthedocs.io/en/latest/user_guide/data_loading_and_saving.html#dicom-data)?
