Myocardial tissue characterization by combining late gadolinium enhancement imaging and percent edema mapping: a novel T2 map-based MRI method in canine myocardial infarction
Background: Assessing the extent of ischemic and reperfusion-associated myocardial injuries remains challenging with current magnetic resonance imaging (MRI) techniques. Our aim was to develop a tissue characterization mapping (TCM) technique by combining late gadolinium enhancement (LGE) with our novel percent edema mapping (PEM) approach to enable the classification of tissue represented by M...
متن کاملMyocardial Viability Imaging using HYPR-based MRI Techniques
INTRODUCTION Assessing myocardial viability in patients with coronary artery disease and left ventricular dysfunction can be critical to determine which patients might benefit from revascularization [1]. Delayed-enhancement MR imaging (DE-MRI) has shown promise in distinguishing healthy myocardium from infarcted myocardium since infarcted myocardium exhibits higher signal than normal myocardium...
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 کاملMean apparent propagator (MAP) MRI: A novel diffusion imaging method for mapping tissue microstructure
Diffusion-weighted magnetic resonance (MR) signals reflect information about underlying tissue microstructure and cytoarchitecture. We propose a quantitative, efficient, and robust mathematical and physical framework for representing diffusion-weighted MR imaging (MRI) data obtained in "q-space," and the corresponding "mean apparent propagator (MAP)" describing molecular displacements in "r-spa...
متن کاملA novel constrained texture mapping method based on harmonic map
In this paper, we present a novel constrained texture mapping method based on the harmonic map. We first project the surface of a 3D model on a planar domain by an angle-based-flattening technique and perform a parametrization. The user then specifies interactively the constraints between the selected feature points on the parametric domain of the 3D model and the corresponding pixels on the te...
