Strain rate imaging differentiates transmural from non-transmural myocardial infarction: a validation study using delayed-enhancement magnetic resonance imaging.
OBJECTIVES The aim of this study was to determine if strain rate imaging (SRI) correlates with the transmural extent of myocardial infarction (MI) measured by contrast-enhanced magnetic resonance imaging (Ce-MRI). BACKGROUND Identification of the transmural extent of myocardial necrosis and degree of non-viability after acute MI is clinically important. METHODS Tissue Doppler echocardiograp...
متن کاملUse of three-dimensional ultrasonography of the eye and measurement of optical long axis in dog
This study was conducted to determine the use of three-dimensional ultrasonography (3DU) in ocular imaging of the dog and measuring of its optical axis. 12 healthy mixed-breed dogs including 6 males and 6 females were studied. 3DU of the eyes were done using a 5–12 MHz linear trapezoid transducer. 3DU of the eyes were evaluated and the normal optical long axis through a line between the cornea ...
متن کاملQuantification of Regional Myocardial Function following Acute Myocardial Infarction by Ultrasonic Strain Rate and Strain Imaging
Objectives: The rapid diagnosis and early risk stratification of patients presenting with acute myocardial infarction (AMI) is important. In experimental setting ultrasonic strain rate (SR) and strain (S) have been shown to identify changes in deformation predictive of ischemia. We sought to evaluate and compare regional myocardial function at “the risk zone” (ARZ) supplied by the culprit coron...
متن کامل"Transmural" versus "subendocardial" myocardial infarction: an electrocardiographic myth.
In 1980, Pipberger and Lopez (1) published an excellent review entitled" 'Silent' Subendocardial Infarcts: Fact or Fiction." They noted that the attempt to distinguish transmural from subendocardial infarcts on the basis of presence or absence of Q waves was not justified by any clinical, pathologic or experimental data. The authors observed that this common misconception arose from a single fl...
متن کاملCombined long- and short-axis myocardial perfusion cardiovascular magnetic resonance.
PURPOSE To date, myocardial perfusion cardiovascular magnetic resonance (CMR) has been reported in single and multiple short-axis slices. Three short-axis planes can assess 16 segments of the standard 17-segment myocardial model, but this approach fails to assess the ventricular apex that requires at least one long-axis plane. We therefore evaluated the feasibility and benefit of combined long-...
