Standardized validated protocols permit to compare different PMCTA images and make it more easily to defend a case in court. In addition to the well-known technique by Grabherr et al. (2011) which is using paraffin oil as a carrier substance, water-soluble polyethylene glycol 200 (PEG200) can be used in combination with the contrast agent Accupaque\u00ae 300. As to date, there exists no standardized protocol for the use of this contrast agent mixture, the aim of this study was to develop a protocol using it. Between 2012 and 2022, 23 PMCTA with PEG200 and Accupaque\u00ae300 were performed at the University Centre of Legal Medicine Lausanne (Switzerland) and the Institute of Forensic Medicine Munich (Germany). The images obtained were evaluated regarding the opacification of the vessels and possible artefacts. The best image quality was obtained with a mixing ratio of 1:15 (Accupaque\u00ae300:PEG200) and a perfusion volume of 1000\u00a0ml in the arterial, 1400\u00a0ml in the venous and 350\u00a0ml in the dynamic phase. The infusion rates described by Grabherr et al. were confirmed for the three phases. Overall, the opacification of the vessels was diagnostically sufficient. In 13 cases no opacification of the right coronary artery was observed due to a stratification artefact. By using the PMCTA protocol with PEG200 as a carrier, a good overall image quality can be achieved. This protocol offers the possibility to standardize PMCTA with PEG200.<\/jats:p>","DOI":"10.1007\/s00414-024-03218-y","type":"journal-article","created":{"date-parts":[[2024,4,3]],"date-time":"2024-04-03T04:01:32Z","timestamp":1712116892000},"page":"1437-1446","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Development of a protocol for standardized use of a water-soluble contrast agent with polyethylene glycol in post-mortem CT angiography"],"prefix":"10.1007","volume":"138","author":[{"given":"G.
