| Outline of Final Research Achievements |
The present study investigated the terminal cardiopulmonary pathophysiology with regard to the cause of death by means of postmortem CT data analysis of forensic autopsy cases within 3 days postmortem, using the following indices: the estimated total lung air/gas content and aeration ratio; the virtual morphometric analysis of thoracic and abdominal great vessels; the estimated virtual total heart weight in situ, and estimated heart blood pooling (difference between estimated and measured heart weight) and the cardiac dilatation index (the ratio of estimated to measured heart weight). These parameters showed specific results with regard to the cause of death.The results suggest that the usefulness of applying these parameters as supplementary indicators of the terminal respiratory function, circulatory status, and central congestion to reinforce autopsy findings.
