摘　　要：目的探讨CT椎间盘造影(CTD)诱发青年士兵盘源性下腰痛患者一致性疼痛与腰椎间盘MRI表现的相关性。方法对54例盘源性下腰痛青年士兵行MR检查后,共对152个腰椎间盘进行CTD,分析CTD分型、对比剂剂量、诱发一致性疼痛与MRI表现的相关性。结果青年士兵盘源性下腰痛患者椎间盘内破裂类型主要为CTDⅡ型和Ⅳ型,其分型、对比剂注射剂量与诱发一致性疼痛具有相关性(P<0.01),腰椎间盘MRI表现与CTD诱发一致性疼痛存在明显相关性(P<0.01)。结论 CTD能够定性诊断腰椎间盘内破裂,进一步确定责任椎间盘;MRI改变可能与青年士兵盘源性下腰痛的病因相关。Objective To explore correlation of MRI findings and CT discography （CTD） with provocative concordant pain in young soldiers with discogenic low back pain （DLBP）. Methods Totally 54 young soldiers （152 discs） with DLBP underwent MR scanning and CTD. Correlation among CTD types, dose of contrast medium, concordant pain by discography and MRI findings were evaluated. Results Internal disc disruption （IDD） of young soldiers with DLBP mainly included CTD Ⅱ and Ⅳ. CTD types and dose of contrast medium correlated with concordant pain by CTD （P〈0.01）. MRI findings of discs correlated with provocative concordant pain by CTD （P〈0.01）. Conclusion CTD can directly show internal disc disruption, identify the symptomatic disc. Changes on MRI might indicate discogenic pain in young soldiers with DLBP.
