It is important that DICOM databases have the correct information in DICOM tags which are updated by Hl7 ADT, ORM and ORU messages. This becomes even more relevant for ensuring that clinical information is intact after migration to the new supplier. Comments please
I appreciate your good work, but I would make sure that you don't re-invent the wheel: there is a HL7 mapping to MWL defined as part of IHE, see radiology, TF volume 2, appendix B.

The reason for doing this exercise is for VNA (rather than DMWL).
Most Trusts are buying a VNA which will be used for a. image display via XDS consumer or other DICOM viewers b. data migration at the end of contract c. Image transfer via XDR, IEP etc
It is really important that clinical information is present and visible on the display systems when they display from VNA archive.
When images are sent from modalities they do NOT contain the following DICOM tags 1. NHS no 2. patient address 3. Referring Consultant/GP 4. Specialty of the Referring Consultant/GP 5. Reason for cancellation of study etc These are very important pieces of clinical information for clinicians managing patients on a day to day basis.
A VNA that takes ADT messages from PAS and HL7 ORM and ORU messages from RIS, will update the DICOM tags with the correct information, so that display systems will be able to display them correctly, and clinicians will have the information they need. For VNAs to be useful they must contain adequate and correct clinically useful clinical information.
I have had some feedback from 2 DICOM experts --who have more knowledge than me. Here is an updated and corrected document.
Any comments and corrections will be very gratefully received.
I have converted the above document to an easy to understand table mapping NHS clinical terms to HL7 fields and DICOM tags. This will help customers, RIS, PACS and VNA vendors to understand our needs in NHS
