Understanding the dynamic process following clot formation and lysis in relevant animal models is of interest in order to understand the mechanism underlying human disease and to develop therapeutic approaches. The results demonstrate for the first time by means of MRI the dynamics of clot lysis in vivo in a rat model of venous thrombosis in the presence of an antifibrinolytic agent. Delayed thrombus lysis rate was measured in treated animals compared to controls. This model could be useful for translation between In Vitro and in vivo results and for bridging to clinical results when evaluating thrombolytic and fibrinolytic agents.
