Post-mortem computed tomography angiography utilizing barium sulfate to identify microvascular structures: a preliminary phantom model and case study

Publication date: Available online 16 November 2016 Source:Journal of Forensic Radiology and Imaging Author(s): Wieke Haakma, Marianne Rohde, Lidy Kuster, Lars Uhrenholt, Michael Pedersen, Lene Warner Thorup Boel We investigated the use of computer tomography angiography (CTA) to visualize microvascular structures in a vessel-mimicking phantom and post-mortem (PM) bodies. A contrast agent was used based on 22% barium sulfate, 20% polyethylene glycol and 58% distilled water. A vessel-mimicking phantom identified small vessels. Intercostal arteries and veins were visualized in four males and one female without known vascular lesions. Microscopy confirmed the filling of vascular structures down to 8 μm without extravasation.
