Code | Display | Definition |
CentralLucent | These are rounded calcifications with a lucent center usually representing dermal calcifications. Larger calcifications with lucent centers may be due to oil cysts/fat necrosis and may follow surgery or trauma. | These are rounded calcifications with a lucent center usually representing dermal calcifications.

EqualDensity | X-ray attenuation of the mass is the same as the expected attenuation of an equal volume of fibroglandular breast tissue. | X-ray attenuation of the mass is the same as the expected attenuation of an equal volume of fibroglandular breast tissue. |
FatContaining | Includes all masses containing fat, such as oil cyst, lipoma, or galactocele as well as mixeddensity lesions such as hamartoma. | Includes all masses containing fat, such as oil cyst, lipoma, or galactocele as well as mixeddensity lesions such as hamartoma. |
HighDensity | X-ray attenuation of the mass is grater than the expected attenuation of an equal volume of fibroglandular breast tissue. | X-ray attenuation of the mass is grater than the expected attenuation of an equal volume of fibroglandular breast tissue. |
LowDensity | X-ray attenuation of the mass is less than the expected attenuation of an equal volume of fibroglandular breast tissue. | X-ray attenuation of the mass is less than the expected attenuation of an equal volume of fibroglandular breast tissue. |
