• Other applications, such as evaluation of myocardial perfusion and of valvular and ventricular function, are very accurately performed with MRI, but competing modalities, such as single-photon emission computed tomography (SPECT) scanning and echocardiography, are more commonly used in clinical practice.

  • MRI is considered the gold standard in the evaluation of myocardial function. (ecrjournal.com)
  • MRI is now considered the gold standard in the evaluation of myocardial function because of its high accuracy as well as inter- and intra-observer reproducibility. (ecrjournal.com)
  • Currently, the most widely used method to determine myocardial perfusion defects is myocardial perfusion single photon emission computed tomography (SPECT). (biomedcentral.com)
  • Thus, using myocardial perfusion SPECT for determination of MaR in patients with acute coronary occlusion is a major logistic challenge not possible at many hospitals[ 6 ]. (biomedcentral.com)
  • CT myocardial perfusion imaging (SPECIFIC trial). (stanford.edu)
  • Furthermore, it has been suggested that the endocardial extent of infarction as assessed by late gadolinium enhanced (LGE) CMR can also be used to quantify the MaR. Hence, we sought to assess the ability of endocardial extent of infarction by LGE CMR to predict MaR as compared to T2-weighted imaging. (biomedcentral.com)
  • The ability of endocardial extent of infarction by LGE CMR to assess MaR was evaluated using T2-weighted imaging as the reference method. (biomedcentral.com)
  • No MaR could be determined by endocardial extent of infarction in two patients with aborted myocardial infarction. (biomedcentral.com)
  • This study demonstrated that the endocardial extent of infarction as assessed by LGE CMR underestimates MaR in comparison to T2-weighted imaging, especially in patients with early reperfusion and aborted myocardial infarction. (biomedcentral.com)
  • Thus, time to reperfusion is thought to limit the transmural infarct progression rather than the endocardial extent of infarction. (biomedcentral.com)
  • We investigated the significance of oceanographic (wave impact model), geomorphological (latitude, depth, exposure), and structural (patchiness) factors in predicting impact extent and intensity. (bvsalud.org)
  • Besides its superiority in determining mass and volumes of the heart, structural imaging of myocardial tissue has become the domain of cardiac MRI. (medscape.com)
  • Literature findings on ACAD in NF1 indicated that this mostly occurs in males, showing predilection for the development of aneurysms at the left anterior descending coronary artery, and manifesting predominantly as acute myocardial infarction, inclusively in teenagers, though it may be also asymptomatic as in our case. (bvsalud.org)
  • It is a difficult task and a great responsibility to evaluate and manage patients with acute - and potentially life-threatening - clinical presentations. (ueg.eu)
  • Besides its superiority in determining mass and volumes of the heart, structural imaging of myocardial tissue has become the domain of cardiac MRI. (medscape.com)
  • The assessment of myocardial fibrosis is the most studied application of cardiac magnetic resonance in AS. (bmj.com)
  • Thus, I NaL offers inotropic support, but negatively interferes with cellular and ventricular compliance, providing a new perspective of the biology of myocardial aging and the aetiology of the defective cardiac performance in the elderly. (nature.com)

  • However, remote myocardium may potentially also contribute to the improvement of LV function after therapy, but this contribution has not yet been evaluated. (biomedcentral.com)
  • 4 Nonetheless, in a series of 120 patients who had endoscopic grade IIIb gastro-oesophageal caustic lesions, 16% of patients referred for oesophagectomy based on endoscopy findings had no transmural necrosis present in their surgical specimen. (ueg.eu)
  • The therapeutic algorithm in this setting has long relied on clinical signs of perforation or on endoscopic signs of transmural necrosis (grade IIIb according to the Zargar classification) during emergency upper GI endoscopy performed 3-6h following admission. (ueg.eu)
  • Based on these mechanisms, dissimilarities in the release of cTnI and cTnT are discussed, with potentially important implications for clinical practice. (medscape.com)
  • Biomarkers are the cornerstone of the diagnosis of primary myocardial infarction (MI), but their clinical significance following coronary artery bypass grafting (CABG) is less well understood. (medscape.com)
  • 5 Transmural necrosis was correctly predicted via a CT scan, in most patients, by blurring of the oesophageal wall or perioesophageal fat, or by absence of postcontrast enhancement of the oesophageal wall. (ueg.eu)
  • Overall, CT scan examination had an excellent negative predictive value (NPV) for the presence of transmural necrosis in patients with caustic oesophageal injuries, and it outperformed endoscopy when making the decision to perform urgent surgery for ingestion of caustic agents. (ueg.eu)
  • The detection of replacement fibrosis by late gadolinium enhancement offers incremental prognostic information in these patients. (bmj.com)
  • To assess the relationship between improved regional and global myocardial function in patients with ischemic cardiomyopathy in response to β-blocker therapy or revascularization. (biomedcentral.com)
  • In patients with chronic ischemic LV dysfunction, β-Blocker therapy or revascularization resulted in a similar improvement of global systolic LV function. (biomedcentral.com)
  • Recent estimations reveal that 4.9 million patients suffer from chronic heart failure in the United States, indicating the magnitude of this major health care problem [ 1 ]. (biomedcentral.com)
  • We sought to define the contribution of regional myocardial segments to the improvement of global systolic LV function in patients after medical therapy or revascularization. (biomedcentral.com)
