Translabial Color Doppler Urodynamics
International Urogynecology Journal, 2001Color Doppler ultrasound is a new method for documenting fluid leakage in the setting of videourodynamic testing. In order to compare color Doppler ultrasound with traditional fluoroscopic imaging we performed a prospective blinded comparative clinical study.

Ultrasound in Medicine & Biology, 1985
Le doppler bidimensionnel offre pour la premiere fois une image bidimensionnelle non invasive en temps reel de la morphologie et de la circulation intracardiaque simultanee. Il fournit des informations hemodynamiques concernant la gravite de la regurgitation et dans une certaine mesure des lesions stenosantes par la representation en temps reel du jet ...

Nature, 1987
AbstractBy simultaneous processing of frequency, phase, and amplitude information in the backscattered ultrasound signal, new instruments now permit the realtime display of high‐resolution grey scale images of tissue combined with the simultaneous display of flow data from vessels within the scan plane.

1991
In the last several years, color Doppler imaging has grown rapidly in clinical application. It was introduced for echocardiography instrumentation in 1984, for peripheral vascular imaging in 1986, and for general radiology use in 1987, and is now included on the vast majority of high-performance ultrasound systems placed in the United States and Europe

Hysterosalpingography with color Doppler ultrasonography
American Journal of Obstetrics and Gynecology, 1991To assess the accuracy of the diagnosis of tubal occlusion with the use of color Doppler flow ultrasonography and hysterosalpingography, 129 infertile women were studied. All 129 women had the procedure performed with an ATL Ultramark 9 (Advanced Technology Laboratories, Bothel, Wash.) color Doppler ultrasonography machine. Eighty-five of the 129 women

Color Doppler sonography in hypothyroidism
European Journal of Ultrasound, 2003The value of color Doppler sonography in thyroid disease continues to be a matter of debate. Over the past few years, several studies have proved unable to yield unequivocal results. Only a few studies concerning color Doppler sonography in patients with hypothyroidism have been published.89 patients with hypothyroidism have been evaluated.

Reproducibility of color Doppler imaging
Graefe's Archive for Clinical and Experimental Ophthalmology, 2009The aims of this study were: (1) to determine the intra-subject and inter-observer variability of color Doppler imaging (CDI) measurements and readings of the retrobulbar blood vessels, (2) to compare the difference invariability of CDI parameters in non-glaucomatous controls versus glaucoma patients, and (3) to provide calculations of minimum sample ...

Color Doppler Imaging in Uveitis
European Journal of Ophthalmology, 1997Purpose. To evaluate the vascular hemodynamic changes that can be detected with color Doppler imaging (CDI) in diagnosis, differential diagnosis and prognosis of uveitis with different etiologies including Behçet's disease. Methods. Four groups consisting of healthy volunteers, uveitis patients with different etiologies and Behçet's disease patients ...

Gallbladder perforation: color Doppler findings
Abdominal Imaging, 2002Gallbladder (GB) perforation is a life-threatening complication of acute cholecystitis, and early diagnosis prevents delay in patient management. We present two cases of GB perforation diagnosed by color Doppler ultrasonography. Each clearly showed a flow signal passing through the perforated site, leading to prompt and successful surgical treatment ...
