WebThe Hounsfield scale is a semiquantitative method of measuring radiograph attenuation. Typical Hounsfield unit (HU) values are adipose tissue, −20 to −150 HU, and kidney, 20 to 50 HU. If an adrenal mass measures <10 HU on nonenhanced CT, the likelihood that it is a benign adenoma is close to 100%.
