  Code	Display
  ClusteredDistribution	Clustered distribution	Grouped (historically, "clustered") This term should be used when relatively few calcifications occupy a small portion of breast tissue. The lower limit for use of this descriptor is usually when 5 calcifications are grouped within 1 cm of each other or when a definable pattern is identified. The upper limit for use of this descriptor is when larger numbers of calcifications are grouped within 2 cm of each other. [Breast Imaging Reporting and Data System—Ultrasound, Second Edition page 73] Valid for the following modalities: MG.
  DiffuseDistribution	Diffuse distribution	Diffuse or Scattered: diffuse calcifications may be scattered calcifications or multiple similar appearing clusters of calcifications throughout the whole breast. Diffuse or scattered distribution is typically seen in benign entities. Even when clusters of calcifications are scattered throughout the breast, this favors a benign entity.

  GroupedDistribution	Grouped distribution	This term should be used when relatively few calcifications occupy a small portion of breast tissue. The lower limit for use of this descriptor is usually when 5 calcifications are grouped within 1 cm of each other or when a definable pattern is identified. The upper limit for use of this descriptor is when larger numbers of calcifications are grouped within 2 cm of each other. [Breast Imaging Reporting and Data System—Ultrasound, Second Edition page 74] Valid for the following modalities: MG.
  LinearDistribution	Linear distribution	These are calcifications arrayed in a line. This distribution may elevate suspicion for malignancy, as it suggests deposits in a duct. Note that both vascular and large rod-like calcifications also are usually linear in distribution, but that these typically benign calcifications have a characteristically benign morphology. [Breast Imaging Reporting and Data System—Ultrasound, Second Edition] Valid for the following modalities: MG.
  RegionalDistribution	Regional distribution	Scattered in a larger volume (> 2 cc) of breast tissue and not in the expected ductal distribution. Regional distribution according to the BI-RADS atlas would favor a non-ductal distribution (i.e. benignity) [https://radiologyassistant.nl/breast/breast-calcifications-differential-diagnosis] Valid for the following modalities: MG.
  ScatteredDistribution	Scattered distribution	Scattered distributions are also called diffuse distributions. These are calcifications that are distributed randomly throughout the breast. Punctate and amorphous calcifications in this distribution are almost always benign, especially if bilateral (in both breasts). [Breast Imaging Reporting and Data System—Ultrasound, Second Edition page 70] Valid for the following modalities: MG.
  SegmentalDistribution	Segmental distribution	Segmental: calcium deposits in ducts and branches of a segment or lobe. Segmental distribution would favor a ductal distribution (i.e. malignancy). Sometimes this differentiation can be made, but in many cases the differentiation between 'regional' and 'segmental' is problematic, because it is not clear on a mammogram or MRI where the bounderies of a segment (or a lobe) exactly are.
