Magnetic Resonance Imaging Is Not Reliable in Classifying Anterior Inferior Iliac Spine Morphology Compared to 3-Dimensional Computerized Tomography.

Purpose: The purpose of this study is to determine the reliability of standard magnetic resonance imaging (MRI) evaluation of AIIS morphology compared with three-dimensional (3D) computerized tomography (CT) (reference standard).

Methods: Sixty hips in 30 patients met the inclusion criteria. The images were reviewed and classified by two fellowship-trained orthopedic surgeons.
