Scanning electron microscopy demonstrated starch powder contamination on the stylet tip from a spinal needle after it was lightly touched with nonwashed surgical gloves. A sterile solution of Pantopaque was injected through the spinal needle after the stylet was withdrawn and carried particulate contaminants to a 0.2 micrometer millipore filter. Using both scanning electron microscopy and energy dispersive x-ray analysis, particles of various sized (mostly 5-10 microns) and variable compositions, including starch, talc, and other elements, were identified. Also, glass particles from the Pantopaque vial and plastic particles from the plastic syringe and tubing used in drawing up the Pantopaque were seen. These observations indicate that strict attention to proper technique in myelography is essential in order to eliminate potential cerebrospinal fluid contamination.
扫描电子显微镜显示，在未清洗的手术手套轻轻触碰脊髓穿刺针后，针芯尖端存在淀粉粉末污染。拔出针芯后，通过脊髓穿刺针注入了泛影葡胺无菌溶液，该溶液将颗粒污染物带到了一个0.2微米的微孔滤膜上。利用扫描电子显微镜和能量色散X射线分析，鉴定出了各种大小（大多为5 - 10微米）且成分各异的颗粒，包括淀粉、滑石粉和其他元素。此外，还发现了来自泛影葡胺瓶的玻璃颗粒以及抽取泛影葡胺时所用塑料注射器和管道的塑料颗粒。这些观察结果表明，在脊髓造影术中严格注意正确的操作技术对于消除潜在的脑脊液污染至关重要。
