Operating system:windows11  
Slicer version:5.5.0  
Expected behavior:  
I want to use 3D slicer to automatically delineate the striatum from brain PET/MRI data and obtain radiomics data, but preprocessing is required before segmentation（intensity correction and spatial normalization）  
Actual behavior:I don’t know how to operate and which extension plugin to use？

It’s not directly integrated with Slicer, but you should be able to use SynthSeg on your data and load the results in Slicer for further analysis.
