Abstract

Surgical ligation clips of various materials were scanned in a water-filled phantom to determine what artifacts would be produced. Tantalum clips produced severe image degradation, while stainless steel clips produced less severe degradation. Minimal artifacts were observed with titanium clips. Clips molded from an absorbable polymeric material, polydioxanone, were visible on computed tomography (CT) scans and had the least effect on the CT image.

摘要

对各种材料的手术结扎夹在充满水的体模中进行扫描，以确定会产生哪些伪影。钽夹产生严重的图像退化，而不锈钢夹产生的退化程度较轻。钛夹产生的伪影最少。由可吸收聚合材料聚二氧六环酮模制而成的夹子在计算机断层扫描（CT）中可见，并且对CT图像的影响最小。
