    Abstract. Aims Postmortem magnetic resonance (MRI) imaging is currently evaluated as alternative to traditional autopsy and myocardial infarction plays a key role therein. The aim of this study is to determine the suitability of postmortem MRI in infarction age staging. Methods and results In eight human forensic corpses presenting with a total of 11 myocardial infarcted areas, short-axis.   Handheld echocardiography during hospitalization for acute myocardial infarction. Clin Cardiol. Nov. 40 (11) Jansen CHP, Perera D, Wiethoff AJ, Phinikaridou A, Razavi RM, Rinaldi A, et al. Contrast-enhanced magnetic resonance imaging for the detection of ruptured coronary plaques in patients with acute myocardial infarction.

    Introduction The use of sensitive biomarkers has significantly improved the diagnosis of myocardial infarction (MI), and has been incorporated into the “Universal Definition” of MI (see Chapter 1). However, the diagnosis of MI can still be difficult. There is significant overlap with other disorders that result in myocardial injury (see Chapter 6). Clerio F. Azevedo, Luciano C. Amado, Dara L.

MR imaging plays an important role in evaluation of myocardial infarction, particularly in the areas of diagnosis, risk stratification, prognosis, and assessment of complications. Magnetic resonance (MR) imaging plays an important role in evaluation of various aspects of myocardial infarction (MI).

MR imaging is useful in establishing the diagnosis of acute MI, particularly Cited by: (). Magnetic Resonance Imaging of Acute Myocardial Infarction in Pigs Using Gd-DTPA. Acta Radiologica: Vol. 31, No. 6, pp. Cited by: 5. Over the last decade, imaging of myocardial viability has become a well-established indication in patients suffering from myocardial infarction.

Myocardial viability imaging is routinely performed using 18 F-fluorodeoxyglucose positron emission tomography, single-photon emission computed tomography or magnetic resonance imaging. Only recently have several multi-slice spiral computed tomography Cited by: 9.

Cardiac magnetic resonance (CMR) is the gold-standard technique for noninvasive myocardial tissue characterization. CMR is also the preferred methodology for the identification of potential benefits associated with new cardioprotective strategies both in experimental and clinical trials.

Improvements in therapy for ST-segment elevation myocardial infarction (STEMI) have resulted in a significant decline in mortality rates. The extent of myocardial loss after STEMI (infarct size) is a main determinant of post–myocardial infarction (MI) mortality and morbidity, including heart failure (HF).For this reason, experimental and clinical research is focused on potential therapies.

Clinical and pathological definition of myocardial infarction Myocardial infarction (MI) is the condition when there is evidence in a clinical setting of myocardial necrosis consistent with myocardial ischemia.1 By pathology, MI is defined as myocardial cell death caused by prolonged ischemia.1 Epidemiology of myocardial infarction.

MR imaging is useful in establishing the diagnosis of acute MI, particularly in patients who present with symptoms of MI but outside the diagnostic time frame of altered cardiac enzyme levels or with clinical features of acute MI but without an angiographic culprit lesion.

Cardiac cine magnetic resonance imaging (Cine-MRI), T2-mapping and late gadolinium enhancement (LGE) cardiac imaging were performed at 24 h, 48 h, 72 h and 7 d after myocardial infarction, respectively.

Introduction. The process of ventricular remodeling after acute myocardial infarction (MI) plays an important role in predisposition to heart failure (HF).1 Current morphology-based imaging modalities, such as cardiovascular magnetic resonance (CMR) imaging and echocardiography, provide excellent information about left ventricular (LV) chamber enlargement and dysfunction after MI.2,3 However.

The severe mortality and morbidity of myocardial infarction requests appropriate and accurate detection.
