Analysis of postmortem changes in internal organs and gases using computed tomography data

Highlights • We investigated postmortem changes using CT data. • We analyzed relationships between PMI and lung volume, intrahepatic gas, and intrarectal gas. • Intrarectal gas decreased with postmortem changes, while intrahepatic gas increased. • We constructed an equation for estimation of PMI. •...

Zusammenfassung:	Highlights • We investigated postmortem changes using CT data. • We analyzed relationships between PMI and lung volume, intrahepatic gas, and intrarectal gas. • Intrarectal gas decreased with postmortem changes, while intrahepatic gas increased. • We constructed an equation for estimation of PMI. • Our data may provide a useful index of postmortem changes for estimation of PMI.
