Bright-Contrast Efficiency In Vitro on MRI
(A) T1-weighted spin echo image and T1 map of wild-type (WT) and ferritin-overexpressing (FrT) cells incubated with 0.2 mM MnCl2 for 24 h. Arrow indicates the bright-contrast cell pellet.
(B–E) (B) Tabulated mean T1 value ± SD. The contrast efficiencies of all MR gene reporter systems are compared by measuring relaxation rate versus metal concentration; data are represented as mean ± SD (C–E).
