Detection of blood aspiration in deadly head gunshots comparing postmortem computed tomography (PMCT) and autopsy

Table 2 Grading system for findings suggestive for aspiration within the minor airways as well as the lung

Level	Grade	Minor airways/lung parenchyma
Level	Grade	PMCT morphology	Autopsy
0	None	No ground glass opacities (ggo)	No signs of aspiration
I	Minimal	Few ggos without signs of confluence	Slight blood deposits at the wall of the lungs
II	Moderate	Many ggos, partial confluence	Significant blood deposits at the walls of the lungs
III	Significant	Many ggos, great confluence	Maximum signs of aspiration with complete obstruction of the lumen of the lungs

The scale ranges from “none” to “significant” whereas none means level 0 and significant level III. Descriptive findings for each, PMCT as well as autopsy are given
