How a small animal image was acquired is important data that must be stored with the image. It is relevant to the interpretation of the image. While DICOM defines terminology applicable to other types of images, Supplement 187 defines terminology that is unique to small animal imaging. “Preclinical It includes the following templates, which are interconnected as shown, that include terminology relevant to image acquisition.

For example, consider the
ed standard how an animal image was acquired and which factors could influence the image–was the housing clean or dirty, housing manufacturer
Supplement 187 defines the common data elements with animal applicability that are also used in TCGA, such as estrogen-receptor (ER) negative and positive, to a co-clinical data set.
For example, consider the following research question, made possible through increased DICOM compliance by small animal/co-clinical data.

With small animal/co-clinical data meeting the DICOM standard, researchers could find a mouse with the same kind of tumor and compare its response to various therapies that could help generate sophisticated diagnoses and treatment plans.
Factors that may influence an image
This project generated Supplement 187 to the DICOM standard. The working group that worked on this was DICOM working group 30.

correction proposals
DICOM WG 6 has processed all of the ballot comments and produced the final text for Sup 187, and CPs 1457, 1470, 1471, 1472, 1473 and 1478.
We are still waiting to finalize the new agreement with SNOMED (IHTSDO), so any new SNOMED codes included in Sup 187 and CP 1478 are constrained until then.
So the supplement and CP 1478 are released with this caveat:
"This draft includes SNOMED codes pending approval by IHTSDO for inclusion in the DICOM subset. Until they are so approved, they may be used without a license or fee only in IHTSDO member countries"
which will be removed as soon as the SNOMED agreement is done.
The target date for the SNOMED agreement is the RSNA DICOM Standards Committee meeting on 12/3, though there is no guarantee that we will make that, but it is looking promising.
