While the detection of hemorrhage in clinical medicine
is focused on organs and body cavities forensic imaging
requires reliable analysis of hematomas in subcutaneous
fatty tissue for the reconstruction of events. In 20
healthy volunteers autologous blood was injected into
the subcutaneous tissue of the thigh and repetitive MRI
scans of the artificial hematoma were performed. When
analyzing the final data, by calculating the Michelson
contrast and a morphological evaluation of the hematomas
and the fatty tissue, we came across three major
influence factors (hematoma shape, fatty tissue
structure and hematoma regeneration) for the assessment
of the age of bruises.
