T2 values of aqueous liposomal suspensions containing or not Nanotex in decreasing concentrations.
| Suspension type /dilution a) | T2 (ms) b) | ||
|---|---|---|---|
| x1 | x1/2 | x1/4 | |
| Liposomes w/ nanoparticles | 1.7 ± 0.0 | 3.5 ± 0.0 | 6.6 ± 0.0 |
| Liposomes w/o nanoparticles | 1138.3 ± 34.6 | 1034.3 ± 6.1 | 2228.2 ± 0.1 |
a) The dilutions (v/v) of the liposomal preparations correspond to the original liposomal suspension (5.26 mM PtdCho, x1), 50% (x1/2) or 25% (x1/4). In the liposomal preparations containing Nanotex these dilutions correspond to iron concentrations of 0.5 mg Fe/mL, 0.25 mg Fe/mL and 0.125 mg Fe/mL.
b) T2 values were determined at 1.5 Tesla (22 °C, Bruker Minispec, Rheinstetten, DE) using the inversion recovery sequence.
