This code system http://hl7.org/fhir/us/breast-radiology/CodeSystem/MGDensityCS defines the following codes:
Code | Display | Definition |
CentralLucent | Central lucent | These are round or oval calcifications that range
from under 1 mm to over a centimeter.
They are the result of fat necrosis, calcified debris
in ducts, and occasional fibroadenomas.

Valid for the following modalities: MG. |
EqualDensity | Equal density | (historically, "isodense")
X-ray attenuation of the mass is the same as the
expected attenuation of an equal volume of
fibroglandular breast tissue.

Valid for the following modalities: MG. |
FatContaining | Fat containing | This includes all masses containing fat, such as
oil cyst, lipoma or galactocele, as well as mixed
density masses such as hamartoma.
A fat-containing mass will almost always represent
a
benign mass.

Valid for the following modalities: MG. |
HighDensity | High density | the breast tissue may be called dense if you have
a lot of fibrous or glandular
tissue and not much fat in the breasts.
Having dense breast tissue is common.
Some women have more dense breast tissue than others.

Valid for the following modalities: MG. |
LowDensity | Low density | X-ray attenuation of the mass is less than the expected
attenuation of an equal volume of
fibroglandular breast tissue.
A low density mass may be a group of microcysts.
If such a finding
is identified at mammography, it may very well not
be malignant but appropriately may
be worked up.
