Coronary MRI allows for the assessment of vascular patency and thus is a desirable imaging tool for the follow-up of vascular patency after percutaneous coronary interventions in which stenosis are treated with stents. We show that, coronary MR in the presence of recently introduced resorbable magnesium scaffold seems not feasible for the detection of in-stent restenosis within the first year post-intervention as signal voids caused by the scaffold may be miss-interpreted as stenosis. However, coronary MRI provides a valuable tool to further study the resorption process of magnesium scaffolds and to visualize the artery after complete resorption of the scaffold.
