## Summary of DICOM UID Update Behavior by Hierarchy Level
229229
This table outlines how bulk updates behave at different levels of the DICOM hierarchy—Study, Series, and Instance—highlighting when updates are allowed, whether a SOP Instance UID filter is required, how instances are moved, and the resulting impact on the UID hierarchy.
