Magnetic Resonance Diffusion Tensor Imaging Provides New Insights Into the Microstructural Alterations in Dilated Cardiomyopathy.
Cardiac magnetic resonance (CMR) diffusion tensor imaging (DTI) is a promising technique capable of probing the myocardial microstructure by assessing the myofiber orientation. New technical developments in CMR DTI in recent years have allowed the clinical application of this powerful imaging technique. CMR DTI has been used to study myocardial infarction and hypertrophic cardiomyopathy in pati...
متن کاملBiomimetic phantom for cardiac diffusion MRI.
PURPOSE Diffusion magnetic resonance imaging (MRI) is increasingly used to characterize cardiac tissue microstructure, necessitating the use of physiologically relevant phantoms for methods development. Existing phantoms are generally simplistic and mostly simulate diffusion in the brain. Thus, there is a need for phantoms mimicking diffusion in cardiac tissue. MATERIALS AND METHODS A biomime...

متن کاملHistology of human myocardial laminar microstructure and consideration of its cyclic deformations with respect to interpretation of in vivo cardiac diffusion tensor imaging
Background Cardiovascular magnetic resonance (CMR) diffusion tensor imaging (CDTI) shows potential to interrogate myocardial microstructure and its dynamics in health and disease. It has been suggested that anisotropies of diffusion measured in vivo might be accounted for and need correction by myocardial strains measured macroscopically. However, relations between nano-, microand macro-scale d...
