Post-mortem computed tomography in sudden death by asthma.

Ground glass attenuation (GGA) of the lungs is a common finding of post-mortem computed tomography (PMCT) that is associated with pulmonary congestion and edema due to cardiac failure during the agonal period, or due to post-mortem hypostasis. However, hypo-attenuation of the lung is an atypical finding of PMCT, and is usually a consequence of hypovolemic states before death or postmortem body posture after death. Previous studies have shown a few differential diagnoses, such as hypothermia, massive hemorrhage, asphyxiation by hanging, and dehydration, for hypo-attenuation of the lung.

Lung weight estimation with postmortem CT in forensic cases.

Postmortem computed tomography (CT) is a minimally invasive technique to examine internal organs before a forensic autopsy. The purpose of our study was to estimate lung weight in a forensic setting in cases of various lung states, including fluid accumulation (congestion, edema, hypostasis, and inflammation etc.) using postmortem CT.
