Code | Display | Definition |
AlmostEntirelyFat | Almost entirely fat | A term used to describe breast tissue that is made
up of almost all fatty tissue.
Fatty breast tissue does not look dense on a mammogram,
which may make it easier
to find tumors or other changes in the breast.
Fatty breast tissue is more common in older women
than in younger women.
Fatty breast tissue is one of four categories used
to describe a level of breast
density seen on a mammogram.

ScatteredAreasOfFibroglandularDensity | Scattered areas of fibroglandular density | A term used to describe breast tissue that is made
up of mostly fatty tissue and
also has some dense fibrous tissue and glandular
tissue.
On a mammogram, the dense areas of the breast make
it harder to find tumors or other
changes.
Scattered fibroglandular breast tissue is one of
