total body ct and mr features of Postmortem Change in in hospital deaths
PLOS ONE, 2017Co-Authors: Ivo M Wagensveld, Britt M Blokker, Piotr A Wielopolski, Nomdo S Renken, Gabriel P Krestin, M Myriam G Hunink, Wolter J Oosterhuis, Annick C WeustinkAbstract:Objectives: To evaluate the frequency of total-body CT and MR features of Postmortem Change in in-hospital deaths. Materials and methods: In this prospective blinded cross-sectional study, in-hospital deceased adult patients underwent total-body Postmortem CT and MR followed by image-guided biopsies. The presence of PMCT and PMMR features related to Postmortem Change was scored retrospectively and correlated with Postmortem time interval, post-resuscitation status and intensive care unit (ICU) admittance. Results: Intravascular air, pleural effusion, periportal edema, and distended intestines occurred more frequently in patients who were resuscitated compared to those who were not. Postmortem clotting was seen less often in resuscitated patients (p = 0.002). Distended intestines and loss of grey-white matter differentiation in the brain showed a significant correlation with Postmortem time interval (p = 0.001, p<0.001). Hyperdense cerebral vessels, intravenous clotting, subcutaneous edema, fluid in the abdomen and internal livores of the liver were seen more in ICU patients. Longer Postmortem time interval led to a significant increase in decomposition related Changes (p = 0.026). Conclusions: There is a wide variety of imaging features of Postmortem Change in in-hospital deaths. These imaging features vary among clinical conditions, increase with longer Postmortem time interval and must be distinguished from pathologic Changes.

comparison of attenuation of striated muscle between Postmortem and antemortem computed tomography results of a longitudinal study
PLOS ONE, 2014Co-Authors: Hidemi Okuma, Wataru Gonoi, Masanori Ishida, Go Shirota, Yukako Shintani, Masashi Fukayama, Kuni OhtomoAbstract:OBJECTIVE: We evaluated the Postmortem Changes of striated muscle by comparing computed tomography (CT) images obtained Postmortem and antemortem in the same patients. MATERIALS AND METHODS: We studied 33 consecutive patients who underwent antemortem CT, Postmortem CT, and pathological autopsy in our tertiary care hospital between April 2009 and December 2010. Postmortem CT was performed within 20 h after death and was followed by pathological autopsy. Pathological autopsy confirmed the absence of muscular diseases such as amyotrophic lateral sclerosis, muscular dystrophy, myositis, and myasthenia, in all of the patients. The CT attenuation values of four cardiac muscle sites (anterior wall of the left ventricle, left ventricular free wall, posterior wall of the left ventricle, and the ventricular septum) and two skeletal muscle sites (the pectoralis major muscle and the erector spinae muscle) were compared between antemortem and Postmortem CT using paired t test. RESULTS: Striated muscle had significantly greater attenuation on Postmortem CT than on antemortem CT (P<0.001) in all six tissue sites. No significant association was found between Postmortem Change in the CT attenuation of striated muscle and gender, age, or elapsed time since death. CONCLUSION: This is the first longitudinal study to show hyperattenuation of striated muscle on Postmortem CT images compared with antemortem CT images in the same patients.
