    Hi Maria Braithwaite, I have updated the format to align the template with the new format. The template language has been added. Should 'CT angiography of [body structure]' be the preferred term according to the feedback from the DICOM and the NICIP?

      Hi Yongsheng Gaomany thanks, the PT is to be 'CT angiography of [body structure] with contrast' after consultation it was agreed all descriptions must stipulate contrast to avoid further confusion, thanks, Maria

        Hi Maria Braithwaite, I am a bit unsure about the decision on all descriptions need to be explicit about using contrast. Diagnostic imaging experts do not have different interpretations for 'CT angiography of X body structure'. It means that this term is not ambiguous at all. It might be unclear to modellers whether contrast has been used or not. We have replaced the new FSNs to make it explicit. The new FSN still has the same meaning as 'CT angiography of X body structure'. Otherwise, the existing concepts should be inactivated and replaced by new concepts. For this reason, I would consider 'CT angiography of body structure' is a proper synonym or even preferred term for diagnostic imaging. 

        This should only be appliable to CT imaging modality as explained by the DI experts. The editorial guide for MR angiography of body structure would be different because there are two options, with or without contrast.

          Hi Yongsheng Gao

          The issue of whether contrast should be explicitly stated has been discussed extensively (including consultation with DICOM and NICIP) please see here

          https://jira.ihtsdotools.org/browse/GC-574

          The briefing paper for EAG members is here

          https://docs.google.com/document/d/1oBB8gqLCjQAkFUn6ZH1j1-yu1heZ0OZS24qRvG7LqEg/edit

          The changes have been implemented and are in the early visibility and we have received no further feedback,

          Thanks, Maria
