A retrospective study of the magnetic resonance (MR) images of the lumbar spines of 13 healthy subjects and 30 patients with degenerative changes was done. In the healthy subjects, the vertebral facets, thickness of the cartilage and ligamentum flavum, signal characteristics of the bone marrow, and size of the spinal canal were studied. In the patients with degenerative changes in one of these structures, MR images in the sagittal plane were useful in demonstrating hypertrophy of the ligamentum flavum or the vertebral facets, in grading the degree of foraminal stenosis, and in measuring the sagittal diameter of the spinal cord. MR images in the axial plane facilitated detailed analysis of the facet joint and more accurate measurements of the thickness of the ligamentum flavum and spinal canal diameter. MR images were compared with computed tomography scans in 12 patients.
对13名健康受试者和30例有退变改变患者的腰椎磁共振（MR）图像进行了一项回顾性研究。在健康受试者中，研究了椎间关节、软骨和黄韧带厚度、骨髓信号特征以及椎管大小。在这些结构之一有退变改变的患者中，矢状面MR图像有助于显示黄韧带或椎间关节肥大、对椎间孔狭窄程度进行分级以及测量脊髓矢状径。横断面MR图像有助于对关节突关节进行详细分析，并更准确地测量黄韧带厚度和椎管直径。对12例患者的MR图像与计算机断层扫描进行了比较。
