“…Autopsy, therefore, remains the gold standard when examining orbital roof fractures. The study also showed that CT is also a good tool for detecting retrobulbar hemorrhage as one of the “blind spots” in autopsy [ 19 ]. A study by the authors from France comparing postmortem CT findings with autopsy findings in a set of 236 cadavers showed a correlation in both fractures of the skull and cranial base, which is a different conclusion from previous studies and our findings.…”

A Comparative Study of Intravital CT and Autopsy Findings in Fatal Traumatic Injuries

Objectives: Traumatic injuries are one of the severe health problems of our time. In the 21st Century, approximately 4.5 million people worldwide die each year due to trauma. Computed tomography (CT) is widely used to diagnose injuries and offers information on the specific location and extent of organ and tissue damage. In cases of severe trauma, whole-body CT is increasingly used as a standard diagnostic technique. An autopsy is the final diagnostic examination and is still considered the gold standard in diagnostic methods in medicine. The aim of the study was to assess the reliability and accuracy of CT scan results, as well as limits in detecting trauma for forensic purposes. It aims to compare traumatic findings in the antemortem CT results to those observed at autopsy. Materials and Methods: We conducted a retrospective–prospective study involving 510 deaths due to trauma. We compared selected traumatic changes in the antemortem CT scan results with the autopsy findings. We obtained data with a detailed analysis of autopsy protocols, photographic documentation from the autopsies, and the interpretation of CT scans from medical documentation. In cases of discrepancies in the findings, we borrowed CT scans, which were repeatedly reviewed by clinical radiologists. Results: By comparing the findings of selected injuries detected by antemortem CT and autopsy, we found a correlation of findings in 75.3% and a discrepancy of findings in 24.7% in a set of 510 cases. After repeated targeted assessment of CT images by clinical radiologists in cases of discrepancies in the findings, which were detected by autopsy and undescribed by CT, the discrepancy decreased to 17%. Conclusions: The results of the study are comparable with data from many studies and professional publications. They show that CT compared to autopsy is a good method for diagnosing gunshot wounds to the head and bone fractures, with a limited diagnosis of cranial base fractures, while an autopsy is better for detecting minor injuries to organs and soft tissues.

“…Токсикологические показатели, необходимые для установки причины смерти в результате отравления, может выявить МР-спектроскопия [24]. Использование инструментов виртопсии позволяет оценить труднодоступные участки тела и обнаружить находки, часто упускаемые при классическом вскрытии (например, ретробульбарное кровоизлияние) [33].…”

This paper presents a literature review evaluating virtopsy options, its development over time and the scope of application nowadays. To analyze the literature sources, we searched for the keyword “virtopsy” in Scopus, Web of Science, Medline, PubMed, and RSCI databases for the period 2006–2022, the results included 199 sources. Of these, 73 publications including original and review papers were selected for review. It is known that diagnosis verification and therapy correction are largely possible only thanks to the work of pathologists. The coincidence of the post-mortem diagnosis with the lifetime diagnosis opens up the possibility to optimize the course of therapy in similar cases. The literature analysis allows us to conclude that the level of imaging accuracy and frequency of successful interpretations of post-mortem radiological examinations have increased significantly, the fact being associated both with an improved quality of X-ray optical and scanning equipment, and formation of a relatively extensive database containing previously obtained findings. Thus, virtopsy is currently a powerful auxiliary tool applicable in post-mortem diagnosis. The combined use of classical autopsy and virtopsy can increase the accuracy of diagnosis, which, together with digital data processing and storage tools, will bring the work of specialists to a new level of interdisciplinary interaction.

“…CT scans of the head are not only able to show plain pathologies, such as hemorrhage, tumors and fractures, but also make it possible to derive the sequence of complex fractures and the direction of an inflicted gunshot [64][65][66]. The use of deep learning for CT scans has been investigated in several studies.…”

The use of postmortem computed tomography in forensic medicine, in addition to conventional autopsy, is now a standard procedure in several countries. However, the large number of cases, the large amount of data, and the lack of postmortem radiology experts have pushed researchers to develop solutions that are able to automate diagnosis by applying deep learning techniques to postmortem computed tomography images. While deep learning techniques require a good understanding of image analysis and mathematical optimization, the goal of this review was to provide to the community of postmortem radiology experts the key concepts needed to assess the potential of such techniques and how they could impact their work.
