This study demonstrated the feasibility of simultaneously acquiring T1 and T2-weighted images using dual-echo VISTA sequence. Phantom experiments showed that dual-echo VISTA can provide T1- and T2-weighted images as conventional T1/2 imaging sequences, and the performance of proposed sequence was further validated by in-vivo scan. By assembling flow-suppression, T1 and T2 contrast in one sequence, dual-echo VISTA has its potential to differentiate stages of thrombus more accurately.
