# Clinical Imaging Procedure Naming Conventions

Almost all imaging procedures can be unambiguously expressed in a number of ways. There is a balance between flexibility in language and efficiency in terminology maintenance. Consequently, all variants for imaging modalities are not routinely included in SNOMED CT. Submissions for additional descriptions must be justified explicitly.

At a minimum, procedures are ordinarily expressed with the modality and body site. Existing content may have inconsistencies, but new content should following the naming conventions that follow.

{% hint style="success" %}
The use of *near synonyms* is acceptable for clinical imaging procedures:

For example,

* 79516005 | Renal arteriography (procedure)| has the synonym renal angiography
* 726077005 | Computed tomography arteriography of bronchial artery (procedure)| has the synonym CT *angiography* of bronchial artery
* 709552006 | Computed tomography angiography of iliac artery (procedure)| has the synonym CT *angiogram* of iliac artery

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.snomed.org/snomed-ct-specifications/snomed-ct-editorial-guide/readme/authoring/domain-specific-modeling/procedure/index-1/index.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
