| 3 | Angiography substantive change | The following inquiry was sent to DICOM and the UKTC (NICIP)for input: We have received a CRS request from a member country to add Using substance (attribute) Contrast media (substance) to 418272005 |Computed tomography angiography (procedure)|. The current definition of the concept 418272005|Computed tomography angiography (procedure)| is method computed tomography and procedure site blood vessel structure. The concept does not include using contrast in its definition but has more granular subtypes which do include contrast. The CRS request is only for the attribute Using substance (attribute) = Contrast media (substance) to be added to 418272005 |Computed tomography angiography (procedure)| but this would impact many subtypes. Before we make any changes to this area of content could you please offer an opinion on these questions below 77343006|Angiography (procedure)| does this use contrast in all cases? Does CT angiography use contrast in all cases? Are there imaging modalities that do not use contrast for angiography - for example can magnetic imaging angiography be carried out without using contrast? See for example concept 437731000119100|Magnetic resonance angiography of head without contrast (procedure)|. A revision of the Editorial Guidance will be required in order to make information about this area of content clearer and this is planned for a future release however it would be really helpful if we could have an opinion relating to the questions outlined above. A summary of the responses and impacts on the terminology is found at: Comments have been submitted by Jeff Pierson and Jeremy Rogers . Additional input requested prior to acceptance or modification of the proposal. Most essential question is whether, given the proposed changes, inactivation and replacement is necessary?

| 7 | Additional description types | Jim Case | As discussed in KL. Need a list of proposed description types to send to tech services for implementation. Guidance on use will need to be developed. Current use cases to consider are: Implemented and populated in the International release:
Implemented but NOT populated in the International release (i.e., for use in extensions)
Issues within our current synonyms was identified in an AMIA paper in 2003: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1480077/pdf/amia2003_0949.pdf Discussion: | |

Discussion: | |
| 9 | Impact of concrete domains | Jim Case | Questions for group: With the adoption of concrete domains, would replacement of relationship values from concepts to concrete values require inactivation and replacement of concepts? Would adoption of concrete domains be sufficient rationale to inactivate concepts representing numbers? Is there a use case for retaining the concepts? Report consensus back to TRAG Discussion: | |
| 9 | Morphology (disorder) concepts | Jim Case | SNOMED CT currently has a large number of disorder concepts that solely represent morphologies. E.g. 416462003 |Wound (disorder)|; 416439000 |Lipogranuloma (disorder)|). While all of these are SD by simply using DIsease + morphology, other than as grouping concepts, are these valuable clinical terms. With the advent of ECL it is a simple query to identify all concepts that fit into these morphologies. What should be the editorial guidance for the creation/maintenance of these terms? Additionally, there are of over 5400 "grouper" terms in SNOMED CT. Many of these are abstract and are useful for navigation, but should not be used in clinical recording. There has been some interest in providing these as an exclusion refset in order to prevent them from being selectable for clinical use. However, some of the terms do have limited clinical usefulness (i.e patient reported clinical findings). It has been suggested that a task for the EAG would be to identify: 1) which terms in the list have clinical usefulness, 2) which terms provide meaningful navigational usefulness and 3) which terms should be inactivated.
