Conventional LGE PSIR provides very good contrast between healthy and scar tissue, but scar patterns may be confused with blood signal. Joint LGE bright- and black-blood imaging allows for improved scar contrast and detailed cardiac anatomy. However, many patients with cardiac implantable electronic device (CIED) do not undergo cardiac imaging due to severe hyperintensity artefacts. Here we propose a technology to image myocardial scars with unprecedent scar contrast in patients with CIED by combining bright- and black-blood SPOT imaging with wideband MRI. We showed that wideband SPOT can suppress CIED-related hyperintensity artefacts, while maintaining improved scar contrast and localization.
