Pelvic obliquity

Pelvic obliquity is referred to as one of three parameters contributing to the pelvic orientation and defines the rotation of the pelvis within the coronal plane. It is a potential source of measurement errors on cross-sectional imaging, especially for measurements conducted on axial images if not considered and appropriately corrected .

Practical points

On CT or MRI 3D images it can be easily corrected by reformatting true axial planes.
