“…As in clinical CT, postmortem contrast imaging methods mitigate this disadvantage. Methods of PMCTA are described in animals and humans by use of peristaltic pumps, immersion pumps, or by modified heart‐lung machines . After cannulation of a vessel and de‐aerating the pump, postmortem perfusion is established by infusion of paraffin oil and subsequent infusion of a lipophilic contrast agent (Figs.…”

“…A commercially available pump (Virtangio®, FUMEDICA AG Division Postmortem‐Angio, Luzernerstrasse 91 CH‐5630 Muri AG, Switzerland) used with oil‐based contrast agent (Angiofil®, FUMEDICA AG Division Postmortem‐Angio) is now available for PMCTA in medical forensics . Whole body PMCTA or partial body PMCTA methods allow investigation of luminal and vascular wall disease, identification of anomalous vessels, localization of active bleeding, and evaluation of acute or chronic coronary artery disease in people …”

Imaging studies are often of evidentiary value in medicolegal investigations involving animals and the role of the veterinary radiologist is to interpret those images for courts as an expert or opinion witness. With progressing interest in prosecuting animal crimes and strengthening of penalties for crimes against animals, the participation of veterinary radiologists in medicolegal investigations is expected to increase. Veterinary radiologists who are aware of radiographic and imaging signs that result in animal suffering, abuse, or neglect; knowledgeable in ways radiology and imaging may support cause of death determinations; conversant in postmortem imaging; comfortable discussing mechanisms and timing of blunt or sharp force and projectile trauma in imaging; and prepared to identify mimics of abuse can assist court participants in understanding imaging evidence. The goal of this commentary review is to familiarize veterinary radiologists with the forensic radiology and imaging literature and with the advantages and disadvantages of various imaging modalities utilized in forensic investigations. Another goal is to provide background information for future research studies in veterinary forensic radiology and imaging.

“…There are also reports referring to evaluation and visualization in cases after medical interventions related to the heart and great vessels [17,18]. The publications are aimed not only at diagnostic efficiency but also present different methods of CA administration [10,19,20] with the propositions of standardized protocols [4,21]. As we understand that there are no universal "remedies" for evaluation of all cases, the advances and limitations in the development of examination methods with the use of administration of CA to cadavers were discussed [22,23].…”

“…Centering around the widely available type of immersion pump that had been identified as suitable for PMCTA [12] and that can provide excellent vascular filling [14], such a PMCTA kit was developed. This technical note describes its parts and the first results of a PMCTA using that kit.…”

The high cost of commercial components and parts for post-mortem computed tomography angiography (PMCTA) has resulted in the development of a very low cost PMCTA-kit. It contains ubiquitous parts from hardware stores, and rapid prototyping derived models for 3D-printing. Design specifications have been tested and improved after finite-element modeling. A case study performed in using the final PMCTA kit parts for a PMCTA shows perfect vascular contrast without relevant leaks.
