In this study human cerebral thrombi were quantitatively characterized after their acquisition by mechanical thromectomy. The characterization was based on multi-parametric MRI using 3D T₁-weighted imaging and ADC and T₂ mapping. In the study it was shown that thrombi complex structure can be assessed by ADC and T2 mapping MRI mapping techniques and that the MRI maps of thrombi can be used for prognosis of the mechanical thrombectomy procedure times prior to the interventions.
