In 95% of cases, computed tomography (CT) enables the articular capsule of the hip joint to be directly visualized. Articular effusion in the hip joint can also be recognized in the CT image. In inflammatory arthritis and active osteoarthrosis of the hip joint, thickening of the articular capsule or articular effusion appears in the CT image. In addition, "undulation" of the articular capsule sometimes occurs. However, we have also observed this wavy configuration of the hip joint capsule in discrete latent osteoarthrosis of the hip joint. It is, therefore, unequivocally indicative of disease only when seen in association with articular effusion or thickening of the capsule. Focal fatty accumulation of the capsule distinguished from articular capsule tissue by its low density.
在95%的病例中，计算机断层扫描（CT）能够直接显示髋关节的关节囊。髋关节的关节积液在CT图像中也能够被识别。在髋关节的炎性关节炎和活动期骨关节炎中，CT图像上会出现关节囊增厚或关节积液。此外，关节囊有时会出现“波浪状”。然而，我们在髋关节的离散性潜伏性骨关节炎中也观察到了髋关节囊的这种波浪状形态。因此，只有在与关节积液或关节囊增厚同时出现时，它才明确指示疾病。关节囊的局灶性脂肪堆积通过其低密度与关节囊组织区分开来。
