Lumbar provocation discography is an invasive diagnostic procedure to identify pain originating from within the lumbar discs. Specific morphological changes within the disc, classified as radial fissures, can be imaged following the injection of radiopaque contrast into the nucleus pulposus. The reproduction of concordant low back and/or referred somatic pain to the lower extremity under controlled conditions and the demonstration of annular radial tears are part of a spectrum of internal disc disruption that is separate from disc degeneration. A review of the validity and technique of lumbar discography as well as recently described causes of false positive responses are presented.
腰椎激发性椎间盘造影术是一种侵入性诊断程序，用于识别源自腰椎间盘内部的疼痛。椎间盘内特定的形态学变化，归类为放射状裂隙，可在向髓核注入不透射线的造影剂后成像。在受控条件下再现与下背部和/或下肢相关的躯体疼痛，以及显示环状放射状撕裂，是椎间盘内部紊乱的一部分，与椎间盘退变不同。本文综述了腰椎间盘造影术的有效性、技术以及最近描述的假阳性反应的原因。
