A new way to quantify tissue perfusion with a software assisted technique of standardized dynamic color Doppler sonographic video analysis

Objective: Perfusion evaluation is crucial for many medical decisions. Existing sonographic techniques don't reflect perfused area (RI) or are invasive and demanding (contrast enhancers). We applied the novel PixelFlux-technique of dynamic tissue perfusion measurement to several clinical problems. Method: The PixelFlux-technique measures heart cycle triggered perfused area and mean perfusion velocity of all pixels inside a region of interest and thus calculates perfusion intensity dynamically. Patients with a variety of diseases were investigated (renal, gastrointestinal, tumors). Results: Dynamic tissue perfusi…
