This technology is the first multimodal non-contrast MRI system for evaluating pelvic venous congestion. It integrates 3D venography and 2D flow analysis to quantify reflux and provide both visual and numeric outputs. Validated in over 800 clinical cases and cross-institutionally, it was published in the top-tier journal IJS (JCI 2nd), won Taiwan’s 2024 National Innovation Award, and holds patents in Taiwan and the U.S., with strong clinical and commercial potential.

This technology pioneers non-contrast MRI-based quantitative flow analysis for pelvic venous congestion, integrating 3D venography and 2D flow metrics into a quantifiable, trackable diagnostic workflow. With 82.6% concordance with venography, it is the first MRI module clinically validated and internationally comparable. Results were published in the top-tier journal International Journal of Surgery (2024), demonstrating strong academic originality and global translational potential.

This technology is the first non-contrast MRI protocol integrating MR sequences for venous structure and flow quantification, with high clinical maturity and cross-institutional validation. It supports venous diagnostics, health screening, and pre-surgical evaluation. The prototype is deployed in hospitals, with expansion and commercialization planned, including flow analysis services and international licensing potential.
