Forensic medical differential diagnosis of brain infarctions and hemorrhasis of traumatic genesis by mueller-matrix microscopy

Abstract. The aim of the work is to develop forensic criteria for differential diagnosis traumatic hemorrhages (HTG), ischemic stroke (IS), and nontraumatic genesis (HNG) formation by 3D Mueller-matrix microscopy layers azimuthal-invariant images circular birefringence histological sections brain. Material methods. Native brain taken from 110 corpses were used study in case of: death coronary heart disease - 20 (18.1%) native (group 1 control); HTG 30 (27.3%) 2), IIB 3), HNG 4). Measurement values distribution coordinate parameters polarization at points microscopic was performed location standard Stokes polarimeter. Results. It found that each phase cross-sections field, volume distributions complex amplitudes sensitivity, specificity balanced accuracy statistical analysis invariants dichroism have maximum small shifts corresponding their level. level intergroup differentiation revealed calculating moments 3rd 4th order, which characterize asymmetry excess substance. Conclusions. Excellent (95% 96%) achieved between control group all groups, good (92% 93%) hemorrhage satisfactory (85% 86%) hemorrhagic strokes genesis.
