Abstract

Postmortem computed tomography (PMCT) is becoming a standard method of forensic investigation. Many centers are now augmenting PMCT with contrast agents, particularly to create PMCT angiography (PMCTA). This chapter describes three distinct methods of achieving PMCTA and the contrast agents they use: first, whole body angiographic techniques in Switzerland; second, using cardiopulmonary resuscitation (CPR) to establish circulation in Japan; and third, targeted coronary angiography techniques in the UK. These three methods provide vascular and to a lesser extent parenchymal contrast enhancement information to PMCT. All methods could be adopted in any forensic unit, even when using hospital clinical scanners. The choice of method rests on several factors including cost, local experience, time available on the scanner, and local cultural and religious preferences. Ideally, however, the choice will also rest on using the most suitable method for the individual case. As can be seen from the development of these methods, modifications are possible to the technique and choice of contrast media that would change the information achieved, allowing refinement of each method to suit an individual case. The authors have no doubt that the use of these contrast-enhanced methods will further strengthen the role of PMCT in forensic investigation.
