摘　　要：目的探讨腰椎间盘T2相对值在腰椎间盘退变量化分级中的临床应用价值。方法对78例受试者腰椎间盘T2相对值与腰椎间盘退变Pfirrmann分级的相关性进行分析。结果各级腰椎间盘T2相对值随Pfirrmann分级增高而增大．各级间差异均有统计学意义（P〈O．01）。结论T2相对值可以对腰椎间盘退变进行准确的量化分级。Objective To explore the relative T2 ratio （relative T2 relaxation time） in lumbar intervertebral disc degen- eration. Methods Comparison T2ratio in 390 discs was performed at different anatomic levels and different Pfirrmann grades in 78 patients. Results In every different anatomic levels,the T2 ratio increased while the Pfirrmann grade in- creased,significant differences of the T2ratio were found between other grades. Conclusion Using the T2ratio of lumbar disc can reflect a good degree of lumbar disc degeneration.
