Numerous clinical studies have repeatedly demonstrated the importance of this modality in the diagnostic evaluation of almost every type of cardiac disease from the rarest congenital disorder to the almost ubiquitous sBudget 发表于 2025-3-30 13:05:37

Measurement of Regional Echo Intensity as a Means of Cardiac Tissue Characterization,ss by scattering and reflection. Both these properties are frequency dependent, and the nature of this dependence may be more informative in identifying differences between tissues than values at a single frequency.

Automatic and Interactive Image Processing of 2-D Echocardiogramms for Analysis of Left VentricularDue to the noisy appearance and low reflected signal energy from boundaries characteristic for 2-D echocardiographic images, specific reflection properties and accuracies of automatic and manual border extraction are greatly reduced. Therefore digital processing of two dimensional echocardiogramms in our institution is focused on three basic areas:放大 发表于 2025-3-31 05:38:24

Contrast Echocardiography of the Right and Left Heart,ontaining microbubbles of air and injected into the circulation makes the blood “echogenic” enabling it to be followed on its way through the cardiac chambers. However, the microbubbles contained in solutions are too large to pass a capillary bed. As a consequence, an echo-contrast effect on the lefRotator-Cuff 发表于 2025-3-31 21:30:17
Diagnosis of Interatrial Communications by Contrast Echocardiography,ar dilatation with or without abnormal septal motion and an apparently defective atrial septum can be demonstrated in virtually all ASD patients (1–4). However, these signs lack specificity (2–4). Therefore contrast echocardiography has recently been used for the direct visualization of interatrialDensity 发表于 2025-3-31 22:45:32
