Iliac cortical density line and the iliac tilt. In the lateral X-ray, the iliac cortical density line can be seen as a straight line several centimeters in length around the anterior border of S1, which is considered to reflect the thickness of the cortical bone of the ilium along with the arcuate line of the ilium (a). The iliac tilt (IT) was defined as the angle between the lower (the farther side to the film) iliac cortical density line and the vertical (b)
