Prognostic Value of Cardiac CT Delayed Enhancement Imaging in Patients With Suspected Coronary Artery Disease

ophysiological principle with late gadolinium enhancement (LGE) cardiac magnetic resonance. CTDE imaging can be relatively easily performed by adding a short breath-hold electrocardiogram-gated scan after coronary CT angiography (CTA). Recent studies demonstrated high diagnostic capability of CTDE for detecting LGE (sensitivity 92%, specificity 98%) (1). Addition of CTDE to routine coronary CTA may provide an excellent opportunity for the detection of unrecognized myocardial infarction (MI). We have already reported that stress dynamic CT perfusion with CTDE had incremental prognostic value over CTA (2). However, it is unclear whether adding CTDE alone without CT perfusion has incremental prognostic value over the assessment of coronary artery stenosis by coronary CTA. the purpose of this study was to investigate whether the presence of

CTDE imaging can assist in diagnosing Gd enhancements in cardiac magnetic resonance imaging and may play a significant role in detecting unrecognized myocardial infarctions. However, it is currently unclear whether using CTDE alone has better prognostic value than CTA in evaluating coronary artery stenosis.
