T2 mapping of atherosclerosis plaque allows accurate tissue component characterization. In this study, dual-echo fast spin echo sequence is optimized for the purpose of highly reproducible T2-mapping. Both phantom and in vivo study show that this optimization approach will greatly promote the reproducibility of T2 mapping technique and the tissue characterization reliability of MRI.
