Post-mortem imaging in forensic investigations: current utility, limitations, and ongoing developments

Forensic imaging is a new field with increasing application all over the world. However, its role in legal medicine is controversial, mostly due to the use of undefined and unclear terms. The aim of this article is to describe forensic imaging and to explain the various techniques that pertain to it. Essentially, these methods consist of radiological methods such as conventional radiography, computed tomography, and magnetic resonance imaging, but other techniques such as 3D surface scanning are also employed. Computed tomography can be combined with minimally invasive strategies such as image-guided sampling or post-mortem angiography. We provide an overview of the advantages and limitations of these methods, which must be identified and understood to enable correct application.
