===Post mortem CT angiography===

Post mortem CT angiography for medicolegal cases is a method initially developed by a [[virtopsy]] group. Originating from that project, both watery<ref name="p18430859">{{cite journal |vauthors =Ross S, Spendlove D, Bolliger S, Christe A, Oesterhelweg L, Grabherr S, Thali MJ, Gygax E|title=Postmortem whole-body CT angiography: evaluation of two contrast media solutions.|journal=AJR Am.

While oily solutions<ref name="p17056884"/> require special deposition equipment to collect waste water, watery<ref name="p18430859"/> solutions seem to be regarded as less problematic. Watery solutions also were documented to enhance post mortem CT tissue differentiation whereas oily solutions were not. Conversely, oily solutions seem to only minimally disturb ensuing toxicological analysis, while watery solutions may significantly impede toxicological analysis, thus requiring blood sample preservation before post mortem CT angiography.<ref name="p22704555">{{cite journal |vauthors =Rutty GN, Smith P, Visser T, Barber J, Amorosa J, Morgan B|title=The effect on toxicology, biochemistry and immunology investigations by the use of targeted post-mortem computed tomography angiography|journal=Forensic Sci.
