Abstract
- The hip cartilage and labrum, as the main targets of femoroacetabular impingement, sports‐related or traumatic damage, as well as congenital and developmental abnormalities, have attracted increasing attention with the development of magnetic resonance imaging (MRI) and hip arthroscopy. MRI is a commonly used imaging modality to noninvasively visualize the hip cartilage and labral lesions. However, conventional orthogonal MRI planes encounter unique challenges given the ball‐and‐socket configuration of the hip joint, its anatomically abducted and anteverted orientation, and the thin, closely apposed cartilage enveloping the femoral head and acetabulum. Advancements in hip MRI's radial plane, which is acquired through the center of the hip joint, offer a solution. This technology provides true cross‐sectional images of the cartilage and labrum perpendicular to the curvature of the joint, thereby mitigating the partial‐volume‐averaging effects. The integration of 3.0‐Tesla high field strength and three‐dimensional (3D) acquisition techniques further enhances the capabilities of the radial plane. This combination yields a high signal‐to‐noise ratio, high spatial resolution, high contrast between intraarticular structures, while minimizing partial‐volume‐averaging effects. Such improvements potentially facilitate the comprehensive detection of even minor chondral and labral lesions. The capability for multiplanar reconstruction from a single 3D volumetric acquisition further strengthens the usefulness of the radial plane by aiding in precise localization of hip cartilage and labral lesions, in line with hip arthroscopy findings. These advancements have the potential to standardize MRI evaluations and radiographic reporting systems for hip cartilage and labrum, offering precise guidance for hip arthroscopy. This article presents a comprehensive review of radial plane technology applied to the hip MRI, and discusses the morphological assessment and localization of hip cartilage and labral lesions utilizing this advanced imaging technique.
