Discography means imaging of the intervertebral discs by intradiscal contrast injections. Discography with a combined CT/discography allows a more detailed classification of annular disruption and degeneration. Combined with a pain response registration, discography can be of value in the diagnosis of chronic low back pain with signs of sciatica in cases where other x-ray modalities have failed to explain the source of pain. Among 20 discography examinations there was a correlation between radicular symptoms and annular disruption with contrast leakage to the epidural space, and disc protrusion on CT scanning.
椎间盘造影术是指通过椎间盘内注射造影剂对椎间盘进行成像。CT/椎间盘造影联合检查能够对椎间盘环破裂和退变进行更详细的分类。结合疼痛反应记录，在其他X线检查方式无法解释疼痛来源的情况下，椎间盘造影术对于诊断伴有坐骨神经痛症状的慢性下腰痛可能具有价值。在20例椎间盘造影检查中，神经根症状与椎间盘环破裂伴造影剂漏入硬膜外间隙以及CT扫描显示的椎间盘突出之间存在相关性。
