Dr. Hyodo and colleagues at Nagoya University presented a paper evaluating the complex venous hemodynamics and treatment outcome of Budd-Chiari syndrome using 4D Flow MRI.
They found that 4D Flow MRI of inspiration and expiration provided a visual, quantitative, and objective assessment of physiological venous blood flow dynamics. They report that these were useful for treatment planning and post-treatment assessment of Budd-Chiari syndrome, which is sometimes difficult to understand with CT.
