MRI of MnFe₂O₄ TMAH-MnFe₂O₄ NPs and PEG-b-PCL-MnFe₂O₄ NMs.

Notes: TMAH-MnFe₂O₄ NPs and PEG-b-PCL-MnFe₂O₄ NMs both exhibited a concentration-dependent signal drop in the GRE T₂WI and FSE T₂WI. The signal intensity decreased gradually with the increase of the metal ions concentration, while NMs induced greater hypointensity at an identical concentration compared with NPs.

Abbreviations: MRI, magnetic resonance imaging; NMs, nanomicelles; NPs, nanoparticles; PEG-b-PCL, polyethylene glycol-block-poly(ε-caprolactone); TMAH, tetramethylammonium hydroxide; T₂WI, T₂-weighted imaging; GRE, gradient echo; FSE, fast spin echo.
