Bone hu value
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. WebWhereas 24.58% were found to have a low bone mass (osteopenia) and 10.83% were found to have osteoporosis. The equivalent mean HU was found to be 211.98 ±31.06, 139.64 ±18.58, 87.22 ±15.92 for normal, osteopenia and osteoporosis respectively. Conclusion: The study shows a strong correlation between QCT BMD with HU.
