Synonyms
- Ductal enhancement
Definitions
- Nonmass enhancement (NME): Enhancement discrete from background that is neither focus nor mass
- Linear: Describes distribution of NME
- Arrayed in line (linear) or line that branches (linear branching)
- Distinguish from segmental distribution: Triangle or cone of enhancement with apex pointing to nipple, involving lobe/segment of breast
- Characterize internal enhancement pattern of NME
- Homogeneous: Confluent, uniform
- Heterogeneous: Nonuniform, random pattern, intervening normal parenchyma or fat
- Clumped: Cobblestone pattern, various shapes and sizes, occasionally confluent; suspicious for DCIS
- Clustered ring: Thin rings clustered in periductal stroma; suspicious for DCIS
