What is typically the Hounsfield Unit range for soft tissues?

The Hounsfield Unit (HU) scale is essential in computed tomography (CT) imaging for quantifying radiodensity, allowing for the differentiation of various tissues and substances in the body. Soft tissues typically fall within a Hounsfield Unit range of approximately +30 to +70 HU. This range reflects the relative density of soft tissues compared to water (which is set at 0 HU) and air (which is around -1000 HU).

Soft tissues, such as muscles and organs, have higher atomic densities than water but are less dense than bone, which accounts for their placement in this specific range. The correct understanding of these values is crucial for interpreting CT scans effectively, as proper identification of tissue types can significantly influence diagnostic decisions.

The other options either represent densities beyond soft tissue limits or fall outside the typical ranges for what constitutes soft tissue in CT imaging. Hence, recognizing the right Hounsfield Unit values for varying tissue types is vital for accurate assessment in radiologic practice.
