摘要
目的:评价CT引导下椎间盘造影对椎间盘源性腰痛的诊断价值,分析造影阳性椎间盘的影像表现。方法:对48例拟诊为椎间盘性腰痛的患者行CT引导下椎间盘造影,根据患者的疼痛表现明确是否为椎间盘源性腰痛;并根据达拉斯CT椎间盘造影评价系统(Dallas discogram description,DDD)对造影椎间盘进行分级,评估其与椎间盘源性腰痛的关系。结果:48例中经椎间盘造影确诊为椎间盘源性腰痛患者30例,累及38个椎间盘,按达拉斯纤维环退变分级为2级、3级的椎间盘占阳性椎间盘的63.2%,纤维环撕裂分级为2级、3级的椎间盘占阳性间盘的94.7%。结论:CT引导下椎间盘造影能够清晰显示纤维环撕裂的部位及程度,是目前诊断间盘源性腰痛的可靠方法。
Objective：To discuss the value of CT-guided intervertebral discography in diagnosing discogenic low back pain,and evaluate the radiographic features of positive disc.Method：48 patients suspected of discogenic low back pain underwent intervertebral discography by CT-guidance.Diagnosis was confirmed according to the response of the patients.The intervertebral discs after discography were classified according to the Dallas discogram description （DDD）.The relationship between the Dallas discogram description cliassification and discogenic low back pain was analyzed.Result：30 of 48 patients showed a positive intervertebral discography （62.5%） involving 38 intervertebral discs.According to the DDD for the degeneration of annular fibrosus,the grade 2 and 3 were accounted for 63.2% of positive discs,for disruption of annular fibrosus,the grade 2 and 3 accounted for 94.7% of positive discs.Conclusion：The CT-guided intervetebral discography is a reliable method to diagnose the discogenic low back pain,it can clearly show the rupture site and degree of the annular disruption.
