Lipid-poor adenoma. (a) Unenhanced attenuation values: 19,,8 HU. (b) Portal-phase attenuation values: 132,,9 HU. (c) 5 minutes attenuation values: 58,,3 HU. (d) 15 minutes attenuation values: 39,,6 HU. Absolute percentage wash-out at 5′ : 65,3%. Relative percentage wash-out at 5′ : 55,8%. Absolute percentage wash-out at 15′ : 82,5%. Relative percentage wash-out at 15′ : 70,4%.
