The acetabular labrum plays an important role in hip biomechanical function and stability. Labral tears can result in appreciable clinical symptoms and joint dysfunction and may predispose the hip to chondral damage and osteoarthritis. Magnetic resonance imaging is an effective tool for detecting and characterizing labral tears. Direct magnetic resonance arthrography is the most commonly used and validated technique for evaluating the labrum. However, indirect magnetic resonance arthrography and non-arthrographic magnetic resonance imaging are two less invasive and less resource-intensive techniques that should also be considered. Orthopaedic surgeons and radiologists should strive to develop and implement minimally and noninvasive diagnostic magnetic resonance imaging protocols for the investigation of labral pathology.
髋臼盂唇在髋关节生物力学功能和稳定性中发挥着重要作用。盂唇撕裂可导致明显的临床症状和关节功能障碍，并可能使髋关节易发生软骨损伤和骨关节炎。磁共振成像（MRI）是一种有效检测和诊断盂唇撕裂的工具。直接磁共振关节造影术是最常用和最有效的评估盂唇的技术。然而，间接磁共振关节造影术和非关节造影术 MRI 是两种侵袭性和资源密集度较低的技术，也应予以考虑。矫形外科医生和放射科医生应努力制定和实施微创和非侵入性的诊断性 MRI 方案，以研究盂唇病变。
