Pediatric Annals, 1987
The advancements in Doppler methodology in the past decade have dramatically changed the way we assess children with heart disease. Techniques to determine pressures, gradients, shunt flows, and regurgitant lesions have shifted the noninvasive studies into areas that were strictly the venue of catheterization a decade ago. The more recent color Doppler

Color doppler echocardiography
International Journal of Cardiac Imaging, 1988Color Doppler flow mapping is a useful new imaging modality which provides near real-time information about the direction and character of intracardiac flows. Color Doppler is especially useful in the diagnosis and quantitation of valvular regurgitation, and in the detection of intracardiac shunts. Color Doppler is a useful adjunct to CW Doppler in the

Pediatric Cardiology, 2002
We describe concepts important in the clinical application of continuous wave, pulsed wave, and color Doppler flow imaging. In the second half of this manuscript, the application of these tools in pediatric echocardiography is addressed.

Veterinary Clinics of North America: Small Animal Practice, 1998
Color Doppler imaging (CDI) is a sophisticated form of ultrasound technology that overlays blood flow and velocity information onto a B-mode, two-dimensional, gray-scale image. This imaging technique--also called color Doppler echocardiography, color-coded Doppler, Doppler color-flow imaging, and color-flow imaging--is a type of pulsed-wave Doppler ...

Usefulness of Echocardiography and Doppler Echocardiography in Endomyocardial Fibrosis
Journal of the American Society of Echocardiography, 2000Our goal was to demonstrate the usefulness of echocardiography and cardiac Doppler echocardiography (echo-Doppler) in the diagnosis of endomyocardial fibrosis, an unusual restrictive cardiomyopathy in Argentina.Between 1980 and 1998, we studied 10 women (aged 27 to 58 years) with endomyocardial fibrosis confirmed by surgery and/or endomyocardial biopsy.

Echocardiography with Doppler [PDF]
, 1986 The addition of Doppler hemodynamic studies to two-dimensional echocardiographic imaging has added specificity to the noninvasive diagnosis of some congenital lesions, and it has provided new hemodynamic information in unsuspected areas. As a quantitative tool, Doppler is used to estimate gradients in stenotic lesions, blood flow in the heart and great

Doppler echocardiography in adenotonsillar hypertrophy
International Journal of Pediatric Otorhinolaryngology, 2000Adenotonsillar hypertrophy causing upper airway obstruction may lead to the pulmonary hypertension and cor pulmonale. This study aimed to clarify the diagnostic methods of this complication, besides polysomnography, to find another objective criterion for surgical intervention and to demonstrate the curative effect of adenotonsillectomy on this ...

Fetal Doppler Echocardiography
Clinical Obstetrics and Gynecology, 1989Les auteurs rappellent les particularites du systeme cardiovasculaire fœtal et donnent les indications de son exploration par echographie Doppler. La technique de l'examen du cœur fœtal est ensuite decrite ainsi que les differents traces obtenus. Le chapitre se termine par les applications possibles de cet examen au diagnostic in utero des anomalies ...

Gabor spectra for Doppler echocardiography [PDF]
Medical & Biological Engineering & Computing, 1998 Doppler echocardiography on current ultrasonography machines makes use of short-time Fourier spectrograms (STFTs) to display the patterns of blood velocities in the heart chamber. From these sonologists infer the functional parameters, such as valve area, that have pathological significance.

Doppler Echocardiography and Cardiac Pacing [PDF]
Pacing and Clinical Electrophysiology, 1982 There is a need for a non‐invasive method to evaluate the hemodynamic consequences of pacing. The value of Dop pler echocardiography in assessing relative changes in stroke volume and cardiac output is reviewed. We present preliminary observations illustrating the potential value of Doppler echocardiography in cardiac pacing. (PACE, Vol. 5, July‐August,
