MWL link error - Study Date & Study Time emptied

[Andrea Venanzi]

Hello everyone! I am having an issue linking a study with a MWL entry in dcm4chee-arc 5.22.0. This is the HL7 message I use to add an order to the MWL:

MSH|^~\&|AvalonRIS|DentalRay|DCM4CHEE|DentalRay|20200320122220||ORM^O01^ORM_O01|MSH202003201222201249189236|P|2.5

The issue I having is that by linking a study to an MWL both via UI and via API, the Study Date field (0008,0020) and the Study Time field (0008,0030) are updated and are set to an empty value:

Is there a way to prevent this from happening? Do I have to send two requests, one for the association and one for changing the date and time of the study?

Thank you,

Andrea

Not able to reproduce. The Study Date and Study Time remain intact.

curl -v -X POST -H "Content-type:application/json" -d '{"StudyInstanceUID": "1.2.3.4.5.6.7.8.9.11234.567.1"}' http://localhost:8080/dcm4chee-arc/aets/DCM4CHEE/rs/mwlitems/1.2.3.4.5.6.7.8.9.11234.567.1/SPID/move/113038%5EDCM

Hi Vrinda, thanks for the quick response. When the StudyUID is the same, the date and the time are kept, while in the case that the StudyUID is different between the study to associate and the mwl item, the date and time are deleted. 

Maybe I misuse this association function, what happens in my clinic is that sometimes our Cone Beam CT does not correctly set the study fields read via MWL ending up assigning the access number, the study description and the studyUID autonomously.

By associating this study with the correct MWL item, the study is actually modified with the correct StudyUID, Study Description and Accession Number, but the Study Date and Study Time fields are not copied to the new updated study.

The study before association:

The MWL element:

The studies after association with:

curl -v -X POST -H "Content-type:application/json" -d '{"StudyInstanceUID": "1.2.3.4.5.6.7.8.9.1234567890"}' http://localhost:8080/dcm4chee-arc/aets/DCM4CHEE/rs/mwlitems/1.2.826.0.1.3680043.8.872.73827086.0.26110.2.1/4724/move/113038^DCM

Thank you so much,

Andrea

You may configure Link MWL Entry Update Policy to SUPPLEMENT and retry.

Hi Vrinda, thank you so much for your answer. Setting Link MWL Entry Update Policy to SUPPLEMENT, all work as expected. 

Thank you again!

Andrea

The disadvantage of using SUPPLEMENT instead (default) PRESERVE is, that also Study attributes will be copied from the original to the new Study, which may be actually wrong.
