Five hundred patients with negative or inconclusive pantopaque myelograms were investigated by lumbar discography. Discography remains the ideal complementary examination to demonstrate normal or diseased disc morphology and its findings were confirmed during surgery in 97.8% of explored discs. Discography is also a valuable clinical test since the injection may reproduce the patient's symptoms. Its observations were determinant in the surgeon's decision to explore a disc or not: 97.3% of patients submitted to laminectomy had an abnormal discogram and 73% of these patients experienced reproduction of clinical symptoms during the procedure. Myelography is superior to discography to demonstrate sequestered fragments, pachymeningitis and spinal stenosis, but was nevertheless not helpful in 56% of the patients in whom these diagnoses were made in the operating room.
对500例碘苯酯脊髓造影结果为阴性或不确定的患者进行了腰椎间盘造影检查。椎间盘造影仍是显示正常或病变椎间盘形态的理想补充检查，其结果在97.8%的探查椎间盘中于手术中得到证实。椎间盘造影也是一项有价值的临床检查，因为注射操作可能再现患者的症状。其观察结果对于外科医生决定是否探查椎间盘具有决定性作用：接受椎板切除术的患者中97.3%有异常椎间盘造影表现，其中73%的患者在手术过程中出现临床症状再现。在显示游离碎骨片、硬脊膜炎和椎管狭窄方面，脊髓造影优于椎间盘造影，但对于56%在手术室做出这些诊断的患者而言，脊髓造影并无帮助。
