Changed State

After a user reviews a study, the study may change. For example, new images arrive from the modality. eRAD PACS notifies the user of this by populating the Changed worklist column. If  the EP server registers a change to the study after the study status is Viewed, the Change flag is set to New or Changed.  The Change flag is a worklist parameter that can be used to create a worklist filter. The field value can be None, New or Changed.

New means the study acquired a previously eRAD PACS unregistered image since the last state or report change.

Changed means the study data has been altered in some way, which may or may not be relevant, since the last state or report change.

None or a NULL field denotes all other states.

A user can use this field to create a default reading worklist. Anything New or Changed would typically require review by a radiologist.

Clear the change flag by opening the viewer and either updating the report, or checking the Clear Change Flag box on the popup window that appears when closing a study.
