WebThe HU can be used to quantify different tissues on a CT scan. For example, water has a HU of 0, fat has a HU of -100 to -150, and bone has a HU of +1000. Tumors also have characteristic HUs that can be used to distinguish them from normal tissues. The table below depicts the Hounsfield unit values of various tissues on multidetector CT imaging. Web26 Mar 2024 · Opportunistic bone density screening is the use of routine CT images to extract bone density information to help detect low bone density and osteoporosis. Evaluation is most common in the spine, and CT has the advantage of avoiding confounders like body size, atherosclerotic calcifications, and degenerative changes of the spine that …
