40 patients with spondylolisthesis and/or spondylolysis were studied by magnetic resonance imaging (MR), 12 of whom with correlation to CT. CT proved to be more sensitive in detecting pars defects than MR. Sagittal MR, however, was more accurate in assessing spondylolisthesis than axial CT. At present, CT is superior to MR in demonstrating bony abnormalities. MR appears indicated in the patient undergoing spinal fusion in whom detection of intervertebral disc degeneration in the levels above or below intended fusion may lead to extension of fusion to the degenerated levels. Lack of ionizing radiation makes MR an ideal diagnostic method in evaluating spondylolisthesis in children and adolescents.
对40例腰椎滑脱症和/或椎弓根峡部裂患者进行了磁共振成像（MR）检查，其中12例同时进行了CT检查。结果表明，CT在检测椎弓根峡部裂方面比MR更敏感。然而，矢状面MR在评估腰椎滑脱症方面比横断面CT更准确。目前，在显示骨质异常方面CT优于MR。对于接受脊柱融合手术的患者，MR检查似乎有必要，因为检测预期融合节段上方或下方的椎间盘退变可能会导致融合节段扩展至退变节段。由于无电离辐射，MR是评估儿童和青少年腰椎滑脱症的理想诊断方法。
