The MRI intensities are mean pixel intensities (values between 0 and 4095) of a 20 mm2 region of interest in the center area of each phantom, supplied by the imaging software. Values are shown ± SD.
USPIO: ultrasmall super-paramagnetic iron-oxide. USPIO dose—full = 10  g per 105 cells. half = 5  g per 105 cells, ns: non-significant.
