“…[31][32][33][34] In porcine exvivo experiments distribution defects of injected gadolinium could be simulated within the porcine myocardium, which possibly can be correlated to a disturbed antemortem perfusion as well. 31 A combination of pmMRI and minimally invasive angiography will enhance the diagnostic performance of pm imaging.…”

“…The first systematic research was started in 2004 in the Institute of Legal Medicine in Bern, Switzerland, in the context of the Virtopsy® project. 28 In 2005, Jackowski et al 29 reported preliminary results of a new technique of minimally invasive whole-body PMCTA using a cannulation of the femoral vessels on one side of the body and the injection of meglumine ioxithalamate as a contrast agent. At the same time and same place, first experiments started with a dynamic angiographic analysis of a whole body.…”

Performing a post-mortem multidetector CT (MDCT) scan has already become routine in some institutes of forensic medicine. To better visualize the vascular system, different techniques of post-mortem CT-angiography have been explored, which can essentially be divided into partial-and whole-body angiography techniques. Probably the most frequently applied technique today is the so-called multiphase post-mortem CT-angiography (MPMCTA) a standardized method for investigating the vessels of the head, thorax and abdomen. Different studies exist, describing its use for medicolegal investigations, and its advantages as well as its artefacts and pitfalls. With the aim to investigate the performance of PMCTA and to develop and validate techniques, an international working group was created in 2012 called the "Technical Working Group Post-mortem Angiography Methods" (TWGPAM). Beyond its primary perspective, the goals of this group include creating recommendations for the indication of the investigation and for the interpretation of the images and to distribute knowledge about PMCTA. This article provides an overview about the different approaches that have been developed and tested in recent years and an update about ongoing research in this field. It will explain the technique of MPMCTA in detail and give an outline of its indications, application, advantages and limitations.

RESUMENLos modernos métodos de imagen, como la CT y la RNM proporcionan datos reales y tridimensionales de la superficie y las estructuras internas corporales. Esta información se almacena en ficheros DICOM (un protocolo estándar en adquisición de imagen radiológica). Sobre esos ficheros pueden realizarse muchos procedimientos de análisis de imagen, tales como visualización interactiva, morfometría, reconstrucciones tridimensionales, etc. Estas tareas son realizadas de una manera no invasiva y no destructiva, pudiéndose almacenar los resultados para documentación del caso. El presente trabajo describe las bases de los procedimientos de análisis de imagen sobre ficheros DICOM dirigidos a propósitos forenses (la llamada "virtopsia"), enfatizando la utilidad del método en Patología, Traumatología Forense y otros campos.La "virtopsia" debe ser considerada no sólo como un procedimientos post-mortem (complementando pero no sustituyendo a la autopsia tradicional), sino como un modo de examinar partes corporales de una manera interactiva, sea en el fallecido o en el sujeto vivo. Ello amplia su utilidad y hace apropiado el procedimiento siempre que se requiera un examen anatómico forense reproducible, preciso, interactivo y en tiempo real.Palabras clave: Análisis de imagen, Proceso de imagen, ficheros DICOM, Radiología digital, Autopsia, Virtopsia, Radiología cadavérica, Radiología asistida por ordenador. Cuad Med Forense 2005; 11(40):95-106 ABSTRACTModern imaging methods, such as radiological CT/MRI scanning provides real, full 3D data of the body surface and internal structures. This information is stored in DICOM files (a standard protocol in radiology image acquisition). Many image-analysis procedures, such as interactive visualization, morphometry, densitometry, three dimensional reconstruction, etc., can be carried-out on these files. These tasks are performed in a non-invasive and non-destructive manner, and the results can be stored in order to document the case.The present paper describes the basis of imageanalysis procedures on DICOM files directed to forensic purposes (socalled "virtopsy"), emphasizing the utility of the method in Pathology, Forensic Traumatology and other fields.The virtopsy must be considered not only as a postmortem procedure (complementing but not substituting the traditional autopsy), but a way to examine body parts in an interactive manner, whatever the subject is dead or alive. That spreads its utility and makes the method appropriate whenever an accurate, real-time, interactive and reproducible forensic anatomic examination is required.
