a–c In vivo T1-weighted MR images of CT26 tumor-bearing mice (slice orientation: axial) at different times post-injection of Dotarem® (CGd = 5.0 mg/kg), US-IO (CFe = 5.0 mg/kg) and FG-HNPs2 (CGd = 5.0 mg/kg). TR = 800 ms, TE = 14 ms. d–f Quantitative analysis of the tumor region after injection of Dotarem®, US-IO and FG-HNPs2 by ΔSNR. The magnetic field was 3.0T
