While the detection of hemorrhage in clinical medicine is focused on organs and body cavities forensic imaging requires reliable localization and analysis of hematomas in soft tissues such as the subcutaneous fatty tissue for the reconstruction of events. To evaluate different MRI sequences with respect to their ability of showing high contrast between hematoma and fatty tissue pork phantoms were examined after injection of small blood volumes, and the reproducibility of volume estimation by manual segmentation was assessed. A TSE T1T2w sequence yielded the best results for volume estimation of hematoma in fatty tissue. Reproducibility of the measurements was excellent.
