Pars basilaris size to estimate fetal and young infant age using forensic post mortem CT imaging Open
Accurate determination of fetal or neonatal age is vital in forensic and medicolegal death investigations. The pars basilaris of the occipital bone, one of the earliest and densest ossification centers, is less susceptible to taphonomic al…

Correlation of pulmonary fat embolism with trauma and resuscitation in children Open
Background This study aims to investigate the correlation between pulmonary fat embolism (PFE), blunt force trauma and the effects of resuscitation in pediatric fatalities. Methods Data for this study covered deaths of 57 children aged 0 t…

Anthropometric weight estimation is less accurate than visual weight estimation in forensic postmortem cases in a Swiss population Open
When the time since death must be calculated forensic pathologists often consider a calculation based on the Henssge nomogram. This calculation requires an estimated body weight. Previous research has indicated that healthcare workers gene…

Mobile forensic photogrammetry in the field: Conservative approach to non-collaborative surfaces Open
Conventional photogrammetry faces challenges with non-textured, transparent, or reflective surfaces, affecting accurate 3D modeling, particularly in forensic documentation. This study evaluates improvements using lower exposure, exposure b…

Virtopsy concept around the world: Institute-based survey of worldwide forensic postmortem imaging Open
Introduction: Forensic routine postmortem imaging in excess of photography and conventional X-ray has been pushed since a few years, in some instances under the name "Virtopsy". It constitutes a pivotal innovation in forensic medicine as i…

Development of A Micro-CT Scanner with Dual-Energy Option and Endovascular Contrast Agent Administration Protocol for Fetal and Neonatal Virtual Autopsy Open
The rate of parental consent for fetal and perinatal autopsy is decreasing, whereas parents are more likely to agree to virtual autopsy by non-invasive imaging methods. Fetal and perinatal virtual autopsy needs high-resolution and good sof…

Visual note - large vitreous hemorrhage in post mortem imaging Open
The significance of vitreous hemorrhages detected after death, particularly in non-traumatic cases, currently seems largely unclear. This obscurity might arise partly because these hemorrhages may go undetected, especially when relying sol…

Illustrated argument for CT-scanning a whole car for the forensic investigation of projectile holes, defects, fragments and possible trajectories Open
Contemporary documentation of a car with bullet defects after a shooting incident can secure the usual tracks and gunshot residue, take photographs, and use trajectory rods and probes. Since the advent of the ”XXL-CT -Scanner” (Fraunhofer …

Comparison of very affordable immersion pump and heart-lung-machine for post mortem CT angiography in forensic pathology – A case-control study Open
Full body post mortem CT angiography (PMCTA) in forensic medicine started on a larger scale with relatively expensive roller-pumps for what in essence seems to be a task consisting of pumping mostly homogenous contrast fluids. At considera…
View article: Virtopsy in a case of intrathoracic dislocation of the head of the humerus: Does this imply an active defense to fall from great height?
Virtopsy in a case of intrathoracic dislocation of the head of the humerus: Does this imply an active defense to fall from great height? Open
To cause a humeral head to be forced into the thoracic cavity, break off, and remain there, a number of requirements may have to be met – including (possibly active) extension of the arm, dislocation of the shoulder, and subsequent impalin…
View article: Effects of blood loss on organ attenuation on postmortem CT and organ weight at autopsy
Effects of blood loss on organ attenuation on postmortem CT and organ weight at autopsy Open
Background Cases of external hemorrhage are difficult to recognize on postmortem computed tomography (PMCT). Purpose To investigate the effects of blood loss on CT attenuation of the spleen, liver, kidneys, and lungs on PMCT and to assess …
View article: Prevalence of calcified epiglottis in postmortem computed tomography. Is there a correlation to failed endotracheal intubation?
Prevalence of calcified epiglottis in postmortem computed tomography. Is there a correlation to failed endotracheal intubation? Open
Objectives: Calcification of the epiglottis is a normal physiological degenerative process, although it can also be a consequence of infection or trauma. There are three possible forensically relevant consequences from epiglottic calcifica…

Overview of the use of 3D printing in forensic medicine Open
In forensic medicine the use of so-called 3D printing is a niche application, whereas developments elsewhere in this field are rapidly advancing worldwide. The most common and widespread technology is fusion deposit modelling with polylact…

The possibility of identifying brain hemorrhage in putrefied bodies with PMCT Open
This paper aims to demonstrate that post-mortem CT (PMCT) can locate intracranial hemorrhages, even in decomposed cases. This is of relevance in that post-mortem decomposition is particularly damaging to the brain tissue’s consistency, res…

Nasal Septum Defects Detected on Postmortem Computed Tomography Open
Nasal septum defects may have forensic relevance because they are associated with various mechanisms, including trauma and cocaine abuse. Like all human body tissues, the nasal septum may be affected by maggots' infestation during postmort…

Fatal Road Traffic Vehicle Collisions With Pedestrian Victims Open
Fatal car-to-pedestrian collisions regularly appear in the forensic pathologist's routine, particularly in places of extended urbanization. Postmortem computed tomography has gained an exceptional role to supplement autopsy worldwide, givi…

Case-study of a user-driven prosthetic arm design: bionic hand versus customized body-powered technology in a highly demanding work environment Open
Research and development of functional prostheses may want to focus on body-powered technology as it already performs on manually demanding and heavy jobs whereas eliminating myoelectric technology's constraints seems out of reach. Relevan…
