Myocardial viability assessment by contrast-enhanced magnetic resonance imaging.
Recent progress in the diagnosis and treatment of coronary artery disease has intensified the need to differentiate viable from nonviable myocardium with accuracy and high spatial resolution. Contrast-enhanced magnetic resonance imaging (MRI) had been investigated as a potential technique to assess myocardial viability for several years (1), before the development of gradient echo-imaging techn...
متن کاملAutomatic Characterization of Myocardial Perfusion in Contrast Enhanced MRI
The use of contrast medium in cardiac MRI allows joining the high-resolution anatomical information provided by standard magnetic resonance with functional information obtained by means of the perfusion of contrast agent in myocardial tissues. The current approach to perfusion MRI characterization is the qualitative one, based on visual inspection of images. Moving to quantitative analysis requ...
متن کاملPrediction of myocardial viability by MRI.
In this regard, the temporal pattern of myocardial contrast enhancement on MRI is reported in this issue of Circulation to be a predictive index of potential myocardial viability for reperfused myocardial infarctions.1 With fast MRI, the firstpass distribution of MRI contrast media indicated that despite patency of the target coronary artery with TIMI 3 flow in all patients, reperfusion at the ...
متن کاملQuantitative 3D Assessment of Myocardial Viability with MRI Delayed Contrast Enhancement
Myocardial viability is a fundamental question in the clinical and therapeutic decision making process. Contrast-enhanced MRI can distinguish between viable and necrotic myocardium in non-invasive manner and with excellent definition of endocardial and epicardial borders. Aim of this study is to propose a software methodology that allows to assess the global, transmural and intramural extent of...
متن کاملImportance of perfusion in myocardial viability studies using delayed contrast-enhanced magnetic resonance imaging.
PURPOSE To investigate whether an extracellular gadolinium-(Gd)-based contrast agent (CA) enters nonperfused myocardium during acute coronary occlusion, and whether nonperfused myocardium presents as hyperintense in delayed contrast-enhanced (DE) MR images in the absence of CA in that region. MATERIALS AND METHODS The left anterior descending coronary artery (LAD) was occluded for 200 minutes...
