In the experimental study of different contrast media, metrizamide has been found to be very safe for epidurography as no clinical, radiologic, or histologic changes after epidural injection were seen. Next in order was meglumine iothalmate. However, sodium containing salts like sodium acetrazoate and sodium iothalmate were found to be very irritating to the nerve roots and the spinal cord and, therefore, should not be used for epidurographic studies.
在不同造影剂的实验研究中，已发现甲泛葡胺用于硬膜外造影非常安全，因为硬膜外注射后未观察到临床、放射学或组织学变化。其次是碘酞葡胺。然而，发现含钠盐如醋氮酰胺钠和碘酞酸钠对神经根和脊髓有很强的刺激性，因此，不应将其用于硬膜外造影研究。
