Rationale for Correction:
When segmenting breast tissue on MR, it was realized that there is no concept in DICOM for breast fibroglandular tissue, nor a Context Group specific to breast segmentation. Add these.
Note that these concepts represent what the tissue is, not how much of the breast is composed of such tissue (such as might be used in mammography reports and CAD, where there is a concern about how much tissue is present and breast density).
Also, they are added as Anatomic Structure category (7192), not Tissue category (7191), since they are intended for use for macroscopic images, though they could probably be used for microscopic images as well; the name of the Context Group is intentionally non-specific in this respect.
Since we are adding the concept for "skin of breast", add it to the context group for Dermatology Anatomic Sites as well.
[Ed.Note: The definition of the NCIt:C114467 is "Breast tissue that contains glandular epithelial and fibrous tissue".]
[Ed.Note: SNOMED CRS RequestID NN1 to add existing concepts used 68192009, 314375000, 58549005, 89749009, 279009002, 82038008, and RequestID NN2 to add new concept for breast fibroglandular tissue]
