| Summary / Zusammenfassung | There are several issues of MR imaging that need to be adapted for the postmortem use of the clinically well implemented MRI technique. Having no ongoing circulation for the distribution of contrast enhancing agents within the corpse the contrast within the images can only be increased by adaptation of the initial scan sequence parameters and improving the postprocessing for visualization. The main object depending feature influencing the quality of postmortem MR images is the body core temperature. As the temperature of corpses varies in a large interval normally ranging from 4° C to 37° C the parameters of the used MR sequences have to be improved for certain body core temperatures. Furthermore, corpses sometimes present with gas within the circulatory system either putrefaction or gas embolism caused. This can also result in image artifacts that are less known from clinical MR images and need to be eliminated. To address these issues is part of the present project. The scanning software and to some extend also the scanning hardware will be adapted and optimized in close collaboration with the supplier. The aim is to develop optimized scan sequences for forensically relevant questions in postmortem scanning conditions. | ||
