Forensic imaging requires reliable analysis of hematomas and their resolution as they can have significant medico-legal consequences. In 30 healthy volunteers autologous blood was injected into the subcutaneous fatty tissue of the thigh and repetitive MRI scans of the artificial hematoma were performed on a 3T scanner. Due to the contrast behavior three relevant age ranges were defined and validated. The generated approach correctly classified all tested hematomas with an age less or equal 24 hours. The development of a reliable and objective MR-based age estimation method of hematomas is in the interest of justice.
