In this study we demonstrated the feasibility of dual-echo balanced SSFP-DIXON sequence with REACT technique for the foot MRA at 1.5T. bREACT dramatically increased the SNR compared to conventional REACT and it could provide excellent contrast between blood vessels and background tissues with high robustness compared with other conventional non-contrast-enhanced MRA methods. This technique would be helpful to assess peripheral blood vessels in the diabetic patients.
