Erratum: Highly sensitive magnetic particle imaging of vulnerable atherosclerotic plaque with active myeloperoxidase-targeted nanoparticles (Theranostics (2021) 11:2 (506-521) DOI: 10.7150/thno.49812)

The authors apologize that the original version of our paper unfortunately contained an incorrect representative image in Figure 4A, where the fluorescence image of an ApoE-/- mouse acquired at 24 h post-injection was saved twice using different color scale bars of fluorescence intensity. We apologize that, during the image assembly, the fluorescence image acquired at 24 h post-injection was mistakenly chosen as the fluorescence image acquired before injection of 5HFeC NPs. The correct version of the Figure 4A is shown below. We confirm that this correction does not affect any original results and conclusions of the paper. The authors apologize for any inconvenience that the errors may have caused.
