Illustration of HU measurement of one vertebra. The largest possible elliptical region of interest (ROI) over an axial level of one vertebra was drawn and HU value was obtained (left). 3 levels of each vertebral body were selected (inferior to the superior end plate, in the middle of the vertebral body, and superior to the inferior end plate) and measured (right). The mean HU value of the three levels was calculated as HU of one vertebra
