Delayed enhancement cardiac magnetic resonance imaging interpretation requires awareness of factors affecting image quality and potential artefacts that mimic focal myocardial scar.
Radiologists interpreting DE-CMR must be aware of factors affecting image quality and potential artefacts that mimic myocardial scar.
Recognition of DE-CMR artefacts is essential to avoid scar misdiagnosis; leaves open optimal sequence standardization.
Delayed enhancement cardiac magnetic resonance (DE-CMR) imaging is used increasingly to identify and quantify focal myocardial scar. Our objective is to describe factors used in the interpretation of DE-CMR images and to highlight potential pitfalls and artefacts that mimic myocardial scar. Inversion recovery gradient recalled echo sequence is commonly accepted as the standard of reference for DE-CMR. There are also alternative sequences that can be performed in a single breath-hold or with free breathing. Radiologists need to be aware of factors affecting image quality, and potential pitfalls and artefacts that may generate focal hyperintense areas that mimic myocardial scar.
