[Forensic radiology : Introduction and overview].

backgroundIn forensic medicine, documentation of findings is essential. During an autopsy, this is usually achieved by photography. However, there are numerous injuries that remain undetected even during a classic autopsy. In recent years, the importance of forensic radiology has grown in many countries to improve the documentation of findings and to increase the quality of post-mortem examinations.

methodsWhile many methods, such as conventional X‑rays or computed tomography, can be transferred quite easily to the post-mortem field, there are other methods that are more difficult to adapt. For example, performing a post-mortem angiography requires a specific concept that allows the vascular system to be filled and a contrast agent to circulate. Performing post-mortem magnetic resonance imaging is also a challenge, as image contrast depends on the temperature of the body being examined. When applying forensic radiology on living persons in the field of "clinical forensic medicine", there are further elements to consider. In particular, the question arises if radiological methods are acceptable for purely forensic medical purposes without a clinical indication.

conclusionThis overview article is intended to explain the various methods of forensic radiology, their areas of application, and their advantages and disadvantages. It also describes important historical developments in the use of forensic radiology and its current spread in German-speaking countries as well as current and future developments. Thanks to this information and a summarizing overview table, clear indications and recommendations for the use of forensic radiology in practice can be obtained.
