“…The literature shows that PMCT with the injection of contrast media, or postmortem CT angiography (PMCTA) [26][27][28][29], performs very well in the search for the cause of unexpected hospital deaths [30] or the detection of vascular injury [31]. Our study could potentially have detected a larger number of injuries if PMCT had been performed with contrast media.…”

Purpose: To study the respective contributions and correlations of autopsy and PMCT in fatal ballistic injuries. Methods: A single-center retrospective descriptive study was carried out over a 10-years period (2008–2017) that included cases of fatal ballistic injuries that had undergone unenhanced PMCT followed by autopsy. In addition to demographics, the main data collected independently at autopsy and PMCT were the number of injuries, their trajectory, distances from the sole of the feet of the entry and exit wounds, projectile caliber and gunshot residue, detailed examination of the injuries, and detection of effusions. Results: Initially, 225 cases were included, of which 158 complete records were analyzed. The mean age of the victims was 41.5 years, and 93% were male. PMCT and autopsy findings were concordant concerning the number of injuries, their trajectory, and distance of the entry and exit wounds from the sole of the feet. Findings were not concordant regarding gunshot residues on the skin (autopsy more efficient) or detection of effusions (PMCT more efficient). The limitations of PMCT were the positioning of the limbs outside the field of acquisition and the impossibility of reliably determining the caliber of the projectiles. Some discrepancies were related to occasionally missing autopsy data, particularly the distance from the sole of the feet or measurements of the volume of effusion. Conclusions: This study provides more detailed knowledge of the accordance of autopsy and PMCT in analyzing fatal ballistic injuries.

“…Previous studies on PMCTA artifacts have reported that artificial ruptures of an artery [ 72 ] or vein [ 73 , 74 ] can occur, although less frequently, due to injection of a contrast agent. PMCTA can be broadly classified into whole-body PMCTA, which contrasts all blood vessels in the body, and focused PMCTA, which contrasts only the arteries perfusing the target organ [ 7 ]. The aforementioned artificial vessel rupture occurred in a systemic PMCTA with a pump injection of a contrast agent.…”

“…However, cardiac arrest in cadavers inhibits contrast-enhanced CT, which is routinely used in clinical practice. This limits the application of PMCT in the diagnosis of spontaneous death, particularly coronary artery ischemic disease [ 1 , 3 , 4 , 5 , 6 , 7 ]. To overcome this limitation, PMCT angiography (PMCTA) has been introduced [ 8 ].…”

Bleeding-Source Exploration in Subdural Hematoma: Observational Study on the Usefulness of Postmortem Computed Tomography Angiography

et al. 2023

In a few cases, postmortem computed tomography angiography (PMCTA) is effective in postmortem detection of cortical artery rupture causing subdural hematoma (SDH), which is difficult to detect at autopsy. Here, we explore the usefulness and limitations of PMCTA in detecting the sites of cortical arterial rupture for SDH. In 6 of 10 cases, extravascular leakage of contrast material at nine different places enabled PMCTA to identify cortical arterial rupture. PMCTA did not induce destructive arterial artifacts, which often occur during autopsy. We found that, although not in all cases, PMCTA could show the site of cortical arterial rupture causing subdural hematoma in some cases. This technique is beneficial for cases of SDH autopsy, as it can be performed nondestructively and before destructive artifacts from the autopsy occur.
