How to query Left and Right information from the CC/MLO view of the MG modality?

Dear community,

From a DICOM file stored on the Orthanc, I need to query the Left and Right side from the CC/MLO view of the MG modality. However, as I open a Patient on the UI, there is no tag available with that information. Making me worry about bringing a possible solution for that.

How should I obtain this information?

Your question seems more related to how the DICOM standard works rather than Orthanc, doesn’t it?
I’m not sure this is the best place to ask for such information…

Kind regards,


Hello Fransisco,

The image laterality tag (R for right, L for left or B for both), which is (0020,0062) is a mandatory tag that should be present in your image.

Even if you may not perform a C-FIND on this tag, you should be able to query it afterwards to filter your search results.

Here is a screenshot of one of our MG instances in the Orthanc Explorer:
