What does Hounsfield units of 75 mean?

Hounsfield units (HUs) are a scale used in computed tomography (CT) to quantify radiodensity. A reading of 75 HUs typically indicates a density similar to that of soft tissue or some types of fluid, which are denser than fat but less dense than bone. This value helps radiologists assess and differentiate between various tissues and potential abnormalities in CT scans.
