RADLEX synonyms : late phase hypointensity; venous phase hypoenhancement; late phase hypoenhancement; portal venous phase hypoenhancement; portal venous phase hypoattenuation; portal venous phase hypointensity; venous phase hypoattenuation; venous phase hypointensity; delayed phase hypoenhancement; deenhancement; washout; delayed phase hypointensity; delayed phase hypoattenuation; late phase hypoattenuation;
Definition : [LIRADS] Reduction in enhancement over time relative to liver following some degree
of arterial phase enhancement, resulting in postarterial extracellular phase hypoenhancement
relative to liver: • For ECA and gadobenate: hypoenhancement in PVP, DP, or both •
For gadoxetate: hypoenhancement in PVP only. Hypointensity in TP or HBP does not qualify
as washout Washout has two subtypes: • Peripheral washout • Nonperipheral washout;
