I’m trying to load Dicom images as multivolume but I’m only getting the option for scalar volume under reader. Why is that? How do I get multivolume?

If you go into advanced mode you might be able to select the multivolume option, but it depends on what’s in the header. The mapping between header tags and mutlivolumes/sequences can have a lot of variants and you may need to look at the code and/or patch the files.
