</div><p>This code system http://hl7.org/fhir/us/breast-radiology/CodeSystem/CalcificationDistributionCS defines the following codes:</p><table class="codes"><tr><td style="white-space:nowrap"><b>Code</b></td><td><b>Display</b></td><td><b>Definition</b></td></tr><tr><td style="white-space:nowrap">ClusteredDistribution<a name="CalcificationDistributionCS-ClusteredDistribution"> </a></td><td>Clustered distribution</td><td>Grouped (historically, &quot;clustered&quot;) 
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.

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.

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).

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.
