Whole-Heart Coronary MRA
Background MRI was first reported to visualize the ostia of the coronary arteries in the late 1980’s (1, 2). Tremendous progress has been made in coronary MRA ever since. One of the milestones was the acquisition of k-space data in a segmented mode (3, 4), allowing collection of an entire data set within multiple heartbeats. Early coronary MRA studies used two-dimensional (2D) technique to acqu...
متن کاملWhole mount heart histology: a new gold standard for myocardial damage validation in experimental cardiac MRI studies?
Introduction: Triphenyltetrazolium chloride (TTC) stain is commonly used for the validation of myocardial damage in experimental cardiac MRI studies using various animal species such as mice, dogs and pigs [1-3]. However, subtle myocardial damage, border zone or infarct heterogeneity associated with myocardial infarction (MI) is difficult to recognize on TTC stains. Although targeted microscopi...
متن کاملThe Effects of in ovo Nanocurcumin Administration on Oxidative Stress and Histology of Embryonic Chicken Heart
This study was designed to evaluate the effects of nanocurcumin (NC) on oxidative stress and histology of embryonic chicken heart. NC was injected into the yolk of 4-day-old embryonic eggs at one of three doses: 10 ppm (NC10 group), 100 ppm (NC100 group), and 1000 ppm (NC1000 group). The control group received normal saline. Oxidative stress in heart tissue was evaluated by measuring malondiald...
متن کاملInteractive Whole-Heart Segmentation in Congenital Heart Disease
We present an interactive algorithm to segment the heart chambers and epicardial surfaces, including the great vessel walls, in pediatric cardiac MRI of congenital heart disease. Accurate whole-heart segmentation is necessary to create patient-specific 3D heart models for surgical planning in the presence of complex heart defects. Anatomical variability due to congenital defects precludes fully...
متن کامل3D Whole Heart Imaging for Congenital Heart Disease
Three-dimensional (3D) whole heart techniques form a cornerstone in cardiovascular magnetic resonance imaging of congenital heart disease (CHD). It offers significant advantages over other CHD imaging modalities and techniques: no ionizing radiation; ability to be run free-breathing; ECG-gated dual-phase imaging for accurate measurements and tissue properties estimation; and higher signal-to-no...
