This value set includes codes based on the following rules:

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

  Code	Display	Definition
  112150	Linear	A shadow resembling a line; any elongated opacity of approximately uniform width [Fraser and Pare].
  122664	Late Contrast Enhancement	Delayed hyperenhancement of a tissue observed in an image acquired after injection of contrast media.
  130593	Partially encapsulated	Partially but not entirely surrounded (bounded) by a distinct tissue layer, such as a smooth low-signal line on MRI.
  130597	Persistent delayed phase: Type 1 curve	Continued increase of signal intensity over time.
  130596	ADC Hypointense	Having lower intensity (darker) than a reference background tissue on apparent diffusion coefficient map.
  130595	ADC Hyperintense	Having higher signal intensity (more intense, brighter) than background tissue on the apparent diffusion coefficient map.
  130594	Completely encapsulated	Entirely surrounded (bounded) by a distinct tissue layer, such as a smooth low-signal line on MRI, in more than one spatial dimension (at least two imaging planes).
  130599	Washout delayed phase: Type 3 curve	Signal intensity decreases after its highest point after its initial rise.
  130598	Plateau delayed phase: Type 2 curve	Signal intensity does not change over time after its initial rise, flat; plateau refers to signal that varies <10% from the peak signal over the duration of the DCE MRI.
  112135	Lobulated	A border shape that is made up of, provided with, or divided into lobules (small lobes, curved or rounded projections or divisions).
  Focal abnormality	Focal abnormality
  130601	Negative DCE	Lack of early enhancement. Diffuse enhancement not corresponding to a focal lesion on T2 and/or DWI MRI. Focal enhancement corresponding to a BPH lesion.
  130600	Positive DCE	Focal, early enhancement corresponding to a focal peripheral zone of transition zone lesion on T2 and/or DWI MRI.
  130604	Focal Contrast Enhancement	Contrast enhancement is concentrated in a focal tissue area.
  130603	Diffuse Contrast Enhancement	Contrast enhancement is non-focal and diffused over a region.
  130602	Early Contrast Enhancement	Contrast-enhanced is observed in the early stage following contrast injection
  112160	Homogeneous	Of uniform opacity or texture throughout [Fraser and Pare].
  Non-focal abnormality	Non-focal abnormality
