中文摘要:
      目的 探讨超短回波时间(UTE)MR序列及常规序列在腰椎间盘软骨终板损伤中的应用价值。方法 对87名志愿者行MR常规序列及UTE序列腰椎成像,分析UTE序列显示的腰椎间盘软骨终板损伤与椎体Modic改变、Pfirrmann椎间盘退变分级之间的相关性。结果 UTE序列成像中,椎体软骨终板显示为非钙化性软骨终板及钙化性软骨终板。L1~S1各节段软骨终板损伤与椎体Modic改变分型、Pfirrmann椎间盘退变分级均呈正相关(P均<0.001)。结论 与MR常规序列比较,UTE序列成像可以清楚显示腰椎间盘软骨终板分层及其损伤,且软骨终板损伤与腰椎退变存在一定关系。
英文摘要:
      Objective To explore the application value of MR ultrashort echo time (UTE) sequence and conventional sequence imaging for displaying lumbar intervertebral disc (IVD) cartilage endplate (CEP) injury. Methods Totally 87 volunteers underwent conventional and UTE lumbar spine MRI. The correlation between UTE sequence of lumbar IVD CEP injury and vertebral Modic changes classification, Pfirrmann disc degeneration grade were analyzed. Results UTE showed linear hyperintense uncalcified CEP and hypointense calcified CEP between nucleus pulposus and vertebral body. There was a positive correlation between cartilage endplate injury in L1-S1 and vertebral Modic changes classification, Pfirrmann disc degeneration grade (all P<0.001). Conclusion MR UTE can clearly show the lamination and damage of CEP, and there is certain relationship between cartilage endplate injury and lumbar degeneration.
