CodeDisplayDefinition
CentralLucent Central lucentThese 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. [https://radiologyassistant.nl/breast/breast-calcifications-differential-diagnosis#benign-calcifications-lucent-centered] 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. [Breast Imaging Reporting and Data System—Ultrasound, Second Edition] Valid for the following modalities: MG.
FatContaining Fat containingThis 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. [Breast Imaging Reporting and Data System—Ultrasound, Second Edition] Valid for the following modalities: MG.
HighDensity High densitythe 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. [https://www.cancer.org/cancer/breast-cancer/screening-tests-and-early-detection/mammograms/breast-density-and-the-mammogram-report.html] Valid for the following modalities: MG.
LowDensity Low densityX-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. [Breast Imaging Reporting and Data System—Ultrasound, Second Edition] Valid for the following modalities: MG.
