Detection of atherosclerotic plaque with iron oxide contrast agents that induce a susceptibility effect in MRI is sometimes hindered by competing sources of negative contrast. Although positive contrast techniques aid in detection, hyper-intensities are often over-emphasised and may thus fail to accurately depict the plaque. We present a true resolution positive contrast method post-processing that provides a more accurate depiction of e.g. SPIO induced susceptibility effect with relation to its source.
