Artery-weighted REACT (REACT-Art), which is optimized the T2prep-time and TFE factor to improve the artery-vein contrast has been proposed, and it provide good artery-dominant contrast compared to conventional REACT. In this study, we focused on the impact of patient positioning to improve the artery-vein contrast with higher robustness, such as raising patient’s heels, putting patient’s heels down, compressing the patient’s legs. we have demonstrated that the patient-positioning like the patient legs to be compressed, and wearing compression stockings might achieve improved artery-vein contrast of REACT-Art with high stability and robustness in the lower extremities without use of contrast-enhancement and ECG-triggering.
