Singlet-assisted diffusion-NMR (SAD-NMR): extending the scope of diffusion tensor imaging via singlet NMR

In this study, long-lived nuclear singlet order methods are combined with diffusion tensor imaging the purpose of characterizing full molecules diffusing freely in large pores up to a millimeter size. Such sizes out reach conventional because limitations imposed by relaxation decay constant longitudinal magnetization. A singlet-assisted methodology able circumvent such is discussed, and new possibilities that it offers demonstrated through simulation experiments on plastic phantoms containing cylindrical channels 1 mm diameter.
