Textural analysis of late gadolinium enhanced magnetic resonance images can discriminate acute from chronic myocardial infarction
Background Late gadolinium enhanced magnetic resonance (LGE MR) imaging is the current standard modality for evaluating the extent of myocardial damage in the presence of ischemic cardiomyopathies (ICM). However it is difficult to differentiate acute from chronic myocardial infarctions (MI) by standard signal intensity thresholding methods. We hypothesize that textural analysis of myocardial in...
متن کاملSubmillimeter diffusion tensor imaging and late gadolinium enhancement cardiovascular magnetic resonance of chronic myocardial infarction
BACKGROUND Knowledge of the three-dimensional (3D) infarct structure and fiber orientation remodeling is essential for complete understanding of infarct pathophysiology and post-infarction electromechanical functioning of the heart. Accurate imaging of infarct microstructure necessitates imaging techniques that produce high image spatial resolution and high signal-to-noise ratio (SNR). The aim ...
متن کاملMyocardial fibrosis delineation in late gadolinium enhancement images of Hypertrophic Cardiomyopathy patients using deep learning methods
Introduction: Accurate delineation of myocardial fibrosis in Late Gadolinium Enhancement on Cardiac Magnetic Resonance (LGE-CMR) has a crucial role in the assessment and risk stratification of HCM patients. As this is time-consuming and requires expertise, automation can be essential in accelerating this process. This study aims to use Unet-based deep learning methods to automate the mentioned ...
متن کاملEmerging Concepts for Myocardial Late Gadolinium Enhancement MRI
Late gadolinium enhancement is a useful tool for scar detection, based on differences in the volume of distribution of gadolinium, an extracellular agent. The presence of fibrosis in the myocardium amenable to be detected with late gadolinium enhancement MRI is found not only in ischemic cardiomyopathy, in which it offers information regarding viability and prognosis, but also in a wide variety...
متن کاملIschemic late gadolinium enhancement.
While research exploring the utility of intravascular gadolinium based contrast agents (GBCA), such as gadofosveset (Vasovist, ABLAVAR) is ongoing, cardiac MR is currently routinely performed with administration of standard extracellular GBCAs, e.g. Gd-DTPA (Magnevist) or Gd-BOPTA (Multihance). LGE is a phenomenon related to the distribution of the extracellular GBCAs. Upon intravenous injectio...
