High quality postmortem human coronary arteriograms are obtained by injecting an acrylamide-bismuth mixture into the isolated aortic root under physiologic pressure. The acrylamide advances to the terminal size (20 micrometer.) arterioles, polymerizes, and remains within the vessels during the processing of tissue for histologic studies. Because the polyacrylamide does not affect the arterial wall morphology or the surrounding myocardium, the acrylamide-bismuth injection technique offers the clarity of the cast-corrosion procedure for postmortem radiograms fo the epicardial and intramural coronary arteries and adds the capability for histologic studies of arterial and myocardial tissues.
通过在生理压力下将丙烯酰胺-铋混合物注入离体主动脉根部，可获得高质量的人体冠状动脉尸检血管造影照片。丙烯酰胺可推进至末梢大小（20微米）的小动脉，发生聚合，并在组织处理以进行组织学研究的过程中保留在血管内。由于聚丙烯酰胺不影响动脉壁形态或周围心肌，丙烯酰胺-铋注射技术为心外膜和壁内冠状动脉的尸检X线照片提供了铸型腐蚀法的清晰度，并增加了对动脉和心肌组织进行组织学研究的能力。
