A prospective study of 200 patients undergoing lumbar radiculography using 10 ml iohexol (240 mgI/ml) was undertaken to determine whether the procedure could be safely performed on an out-patient basis. No statistically significant differences in the incidence and severity of side-effects were found between the 99 out-patients and 101 in-patient controls. Three out-patients had to be kept in hospital at the end of the observation period and a further three out-patients were re-admitted to hospital because of severe side-effects. Out-patient lumbar radiculography is a safe procedure provided there is careful patient selection, adequate advice and easy access to medical help should problems arise following the examination. Adopting this practice considerably reduces the cost of lumbar radiculography and indirectly increases the availability of orthopaedic beds.
对200例接受使用10毫升碘海醇（240毫克碘/毫升）进行腰椎造影的患者进行了一项前瞻性研究，以确定该检查能否在门诊安全进行。99例门诊患者与101例住院对照患者在副作用发生率和严重程度方面未发现统计学上的显著差异。在观察期结束时，有3例门诊患者需留院，另有3例门诊患者因严重副作用再次入院。如果仔细挑选患者、给予充分建议并在检查后出现问题时能方便获得医疗救助，门诊腰椎造影是一种安全的检查方法。采用这种做法可大幅降低腰椎造影的费用，并间接增加骨科病床的可使用量。
