Late Contrast Enhancement |
Delayed hyperenhancement of a tissue observed in an image acquired after injection of contrast media. |
|
130597
|
Persistent delayed phase: Type 1 curve |
Continued increase of signal intensity over time. |
|
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. |
|
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. |

|
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. |
|

|
Early Contrast Enhancement |
Contrast-enhanced is observed in the early stage following contrast injection |
