The objective of this study is to validate two-dimensional (2D) myocardial elastography estimates in canine hearts in vivo against direct sonomicrometry measurements at variable levels of myocardial ischemia induced by the occlusion of the left anterior descending (LAD) coronary artery. Two-dimensional myocardial elastography comprised transmural: 1) 2D (lateral and axial) displacements using 1D cross-correlation...
The blood-brain barrier (BBB) is a specialized brain protection system consisting of endothelial cell, tight junctions and glial processes. BBB is the major limiting factor to therapeutic agents to the brain for disease treatment. Focused ultrasound (FUS) in the presence of microbubbles has the capability to deliver large molecules across BBB. In this study, we qualitatively and quantitatively analyzed...
Myocardial elastography is a novel method for noninvasively assessing regional myocardial function, with the advantages of high resolution and high precision. The purpose in this paper was to isolate the left ventricle from other structures for better displacement and strain visualization. Using a high-resolution (30 MHz) ultrasound system and a retrospective electrocardiogram (ECG)-gating technique,...
In this paper, myocardial elastography (ME), a radio-frequency (RF) based speckle tracking technique, was employed in order to assess the contractility of a myocardium, and validated against tagged magnetic resonance imaging (tMRI) in vivo in normal as well as abnormal cases. Both RF ultrasound and tMRI frames were acquired in 2D short-axis (SA) views from two healthy subjects and one with a history...
