To evaluate the performance of late enhancement dual-energy CT (LE-DECT) for the detection of infarcted myocardium as compared with 1.5-T late enhancement MRI (LE-MRI) in a porcine model of reperfused chronic myocardial infarction, using histopathology as standard of reference. Read more

The purpose of this article is to compare the performance of dual-energy CT with that of 3-T MRI with late enhancement for the detection of chronic myocardial infarction during first-pass coronary CT angiography (CTA). Read more

Electro-cardiogram (ECG)-gated dual energy computed tomography (DECT) of the heart may enable spectral analysis of the myocardium for areas of decreased blood supply in addition to morphological assessment for coronary artery stenosis. We used DECT for evaluating a 49-year-old woman with known coronary artery disease and new onset chest pain. She … Read more

Case history [A] 58-year-old men with 2-vessel CAD and several cardiovascular risk factors, e.g. long-term arterial hypertension, dyslipoproteinemia, was referred for Dual Source CT angiography. Question Dual Source CT angiography for re-evaluation of coronary arteries and potential detection of coronary artery stenoses. Diagnosis/Differential diagnosis [A] Left-ventricular hypertrophy (LVH) most likely due to long-term arterial hypertension; … Read more

Case history 66-year-old man with two-vessel coronary artery disease, chronic myocardial infarction, and persistent atrial fibrillation. Question Assessment of cardiac morphology and left-ventricular function preceding cardiac resynchronization therapy (CRT) with implantable cardioverter-defibrillator (ICD) Diagnosis / Differential diagnosis Two-vessel coronary artery disease (CAD); chronic myocardial infarction with consecutive aneurysm of left-ventricular apex and adherent calcified thrombi Severely … Read more

Case history 43-year-old patient with acute chest pain, not entirely typical for myocardial infarction. ST segment elevation [fig. 1] and enzyme elevation. Echo was normal. Question Myocarditis versus myocardial infarction: Can coronary stenoses/occlusions be ruled out? Diagnosis / Differential diagnosis Chest pain and ST segment elevation are the lead symptoms of acute myocardial infarction. Here, … Read more
