Magnetic resonance (MR) imaging was performed on 15 healthy subjects to define the appearance of the iliopsoas muscle and on 15 patients with iliopsoas disease. Seven patients had tumorous involvement of the muscles, five had inflammatory disease, one had retroperitoneal hemorrhage, one had iliopsoas bursitis, and one had bilateral hypertrophy. MR imaging permitted delineation of the muscles and depiction of the disease condition. Transverse MR images alone almost always provided the necessary data to determine the origin and extent of disease. Sagittal images were occasionally useful in defining the extension of disease into the spine. T1-weighted images provided optimal contrast between the muscles and adjacent tissues, while T2-weighted images were more useful for depicting disease within the muscles themselves.
对15名健康受试者进行磁共振（MR）成像以确定髂腰肌的外观，并对15名患有髂腰肌疾病的患者进行成像。7名患者的肌肉有肿瘤累及，5名患有炎症性疾病，1名有腹膜后出血，1名有髂腰肌滑囊炎，1名有双侧肥大。MR成像能够勾勒出肌肉轮廓并描绘疾病状况。仅横向MR图像几乎总能提供确定疾病起源和范围所需的数据。矢状面图像偶尔有助于确定疾病向脊柱的延伸。T1加权图像能在肌肉与相邻组织之间提供最佳对比度，而T2加权图像对于描绘肌肉本身的疾病更有用。
