摘要: Abstract Objective Experimental fatal models were prepared to investigate the time-related course of lung changes using postmortem CT (PMCT). This study was approved by our institutional animal ethics committee. Materials and methods Twenty-four NZW rabbits (female 24, 2.30–4.30 (mean 3.10)kg) divided into 4 groups; drowning, hypothermia, bag suffocation, Potassium Chloride intravenous (control) group. All individuals examined (Aquilion CX, Toshiba, Japan) on time until detection putrefaction air. The percent aerated volume (%ALV=100*(ALV/total volume)) measured pleural space fluid investigated axial imaging. A paired t -test Bonferroni/Dunn employed for statistical evaluation. Results In intra-group analysis, %ALV showed statistically different periods compared with each pre-image: 4–48h in control, 1–24h 5–6h 1–4h suffocation. inter-group comparison (compared control group), increased suffocation decreased drowning within 12h. remained significantly high hypothermia 24h. earliest times collection group: (20h), (18h), (36h), (95h). Conclusion hypostasis appearance presented differently individual causes death depending time.
