Postmortem CT Angiography Compared with Autopsy: A Forensic Multicenter Study

TLDR
Postmortem CT and postmortem CT angiography and autopsy each detect important lesions not detected by the other method, which may increase the quality of postmortem diagnosis.
Abstract
Purpose To determine if postmortem computed tomography (CT) and postmortem CT angiography help to detect more lesions than autopsy in postmortem examinations, to evaluate the strengths and weaknesses of each method, and to define their indications. Materials and Methods Postmortem CT angiography was performed on 500 human corpses and followed by conventional autopsy. Nine centers were involved. All CT images were read by an experienced team including one forensic pathologist and one radiologist, blinded to the autopsy results. All findings were recorded for each method and categorized by anatomic structure (bone, organ parenchyma, soft tissue, and vascular) and relative importance in the forensic case (essential, useful, and unimportant). Results Among 18 654 findings, autopsies helped to identify 61.3% (11 433 of 18 654), postmortem CT helped to identify 76.0% (14 179 of 18 654), and postmortem CT angiography helped to identify 89.9% (16 780 of 18 654; P < .001). Postmortem CT angiography was superior to autopsy, especially at helping to identify essential skeletal lesions (96.1% [625 of 650] vs 65.4% [425 of 650], respectively; P < .001) and vascular lesions (93.5% [938 of 1003] vs 65.3% [655 of 1003], respectively; P < .001). Among the forensically essential findings, 23.4% (1029 of 4393) were not detected at autopsy, while only 9.7% (428 of 4393) were missed at postmortem CT angiography (P < .001). The best results were obtained when postmortem CT angiography was combined with autopsy. Conclusion Postmortem CT and postmortem CT angiography and autopsy each detect important lesions not detected by the other method. More lesions were identified by combining postmortem CT angiography and autopsy, which may increase the quality of postmortem diagnosis. Online supplemental material is available for this article.

TL;DR: Distinct postmortem imaging modalities can achieve high sensitivities for detecting various findings and causes of death and this knowledge should lead to a reasoned use of each modality.

Relevant findings on postmortem CT and postmortem MRI in hanging, ligature strangulation and manual strangulation and their additional value compared to autopsy – a systematic review

TL;DR: A systematic review of the role of postmortem CT and MRI in cases of hanging and ligature and manual strangulation and compared the detectability of these findings among CT, MRI and autopsy concluded that postmortem MRI is almost equally accurate for the detection of hemorrhages in the neck.

Postmortem computed tomography angiography (PMCTA) and traditional autopsy in cases of sudden cardiac death due to coronary artery disease: a systematic review and meta-analysis.

TL;DR: PMCTA demonstrated a high accuracy in the diagnosis of parietal and luminal coronary changes but was less effective in detecting myocardial ischemia and necrosis, suggesting that PMCTA can improve the performance of the autopsy.

TL;DR: Data Analysis by Resampling is a useful and clear introduction to resampling that would make an ambitious second course in statistics or a good third or later course and is quite well suited for self-study by an individual with just a few previous statistics courses.
