A prospective study was made to evaluate the effect of intrathecal injection of iohexol on brainstem auditory evoked potentials (BAEP) following myeloradiculography, in order to assess its neurotoxicity. Thirty patients who received contrast medium via the lumbar route for myeloradiculography (cervical level = 25 patients, lumbar level = 5 patients) had BAEP examinations before, 2 h and 24 h after myelography. No statistically significant prolongation of absolute and interpeak latencies was found between premyelographic and postmyelographic records. Low incidence (20%) of insignificant clinical adverse effect following myelography was also noted in the same group of patient.
为评估脊髓造影术后鞘内注射碘海醇对脑干听觉诱发电位（BAEP）的影响，以评估其神经毒性，开展了一项前瞻性研究。30例经腰椎途径接受造影剂进行脊髓造影的患者（颈椎水平 = 25例患者，腰椎水平 = 5例患者）在脊髓造影术前、术后2小时和24小时进行了BAEP检查。脊髓造影术前和术后记录之间未发现绝对潜伏期和峰间潜伏期有统计学意义的延长。在同一组患者中还注意到脊髓造影术后临床不良反应发生率较低（20%），且不良反应不明显。
