There is an enhancing mass in the right adrenal gland that measures 4.9 x 4.7 cm.
It enhances heterogeneously with the following attenuation values:
- noncontrast: 39 HU
- arterial phase: 50 HU
- portal venous phase: 92 HU
- delayed phase: 66 HU
This means that the mass has a washout of [(92-62) / (92-39)] x 100 = 57%
The cutoff for adrenal adenoma washout is ~60% or above.
