| Outline of Final Research Achievements |
Gross anatomy lab cadavers were enhanced by drip infusion through the radial artery with oral contrast diluted with formaldehyde solution. In most cadavers, main blood vessels such as the middle cerebral artery and the femoral artery were well enhanced. Contrast solution reached the organs, but enhancement was heterogeneous. This might be due to intravascular thrombi in smaller arteries preventing peripheral enhancement. We did not explore methods on homogenizing enhancement. We did not enhance forensic autopsy cases. Enhancement might potentially displace fluid such as pleural effusion and ascites. We do not know of any method to correlate actual fluid volume with contrast enhanced postmortem CT findings, nor did we explore and assess new methods.
