WebMay 8, 2024 · Hypodensity means that a described structure in a report is darker on CT than the surrounding tissue or organ. It says nothing of the cause. Density on CT is measured with something called hounsfield units. Air and fat have negative numbers, water is close to zero, and structures like soft tissue, blood and bone are higher than zero. The Hounsfield unit (HU) scale is a linear transformation of the original linear attenuation coefficient measurement into one in which the radiodensity of distilled water at standard pressure and temperature (STP) is defined as 0 Hounsfield units (HU), while the radiodensity of air at STP is defined as −1000 HU. In a voxel with average linear attenuation coefficient , the corresponding HU value is therefore given by:
