• Include these codes as defined in http://dicom.nema.org/resources/ontology/DCM

  Code	Display	Definition
  111460	Complex cyst	A fluid-filled sac with greater than normal characteristics.
  111461	Intracystic lesion	A tumor within a cyst.
  111462	Solid mass	A tumor or lesion.
  111287	Normal breast tissue	Normal breast tissue.
  111100	Breast geometry	The surface shape of all or a portion of breast related anatomy.
  111101	Image Quality	Image quality incorporates the following clinical image evaluation parameters: assessment of positioning, compression, artifacts, exposure, contrast, sharpness, and labeling.
  111429	Duct narrowing	An abnormality observed during ductography where the ductal system within the breast appears narrow.
  111102	Non-lesion	A finding or feature that is identified as a non-anatomic foreign object.
  111425	Intraluminal filling defect	An abnormality observed during ductography where the ductal system within the breast fills in an abnormal pattern. Ductography is an imaging study in which a radio opaque contrast media is introduced into the ductal system of the breast through the nipple and images of the ductal system are obtained.
  111129	Clustered microcysts	A cluster of tiny anechoic foci each smaller than 2-3 mm in diameter with thin (less than 0.5 mm) intervening septations and no discrete solid components.
  111426	Multiple filling defect	During ductography an observation of more than one filling abnormality within the breast ductal system.
  111427	Abrupt duct termination	An abnormality observed during ductography where the ductal system within the breast terminates in an unusual fashion.
  111428	Extravasation	Abnormal flowage of contrast media within the breast noted on ductography.
  111130	Complicated cyst	A fluid filled mass most commonly characterized by homogeneous low-level internal echoes on ultrasound.
  111430	Cyst fill	During ductography an observation of the contrast media filling a cyst within the breast.
  111111	Cooper's ligament changes	Straightening or thickening of Cooper's ligaments.
  111112	Mass in the skin	An abnormality noted at imaging within the dermis of the breast.
  111099	Selected region	A specific area of interest noted within an image.
  111113	Mass on the skin	An abnormality noted at imaging on the epidermis of the breast.
  111459	Mass with calcifications	A radiopaque density noted during diagnostic imaging that has associated calcific densities.
