From: Highly sensitive magnetite nano clusters for MR cell imaging
T 2 -weighted MR images of different amounts of RAW267.4 cell (treated with 100 μg/mL particles for 1 h) suspended in Matrigel (0.4 mL) and embedded subcutaneously into the dorsal flanks of mice (arrow head). A: 1 × 104. B: 1 × 105. C: 1 × 106 . Left side: cells treated with SHU555A. Right side: cells treated with the MNCs (63 nm). D: plain Matrigel.
