[Color Doppler ultrasonography in urology].

Progres en urologie : journal de l'Association francaise d'urologie et de la Societe francaise d'urologie, 1995
Due to the development of the duplex mode, combining ultrasound images with Doppler recording, and especially the development of flow colour coding. Doppler is now increasingly used to investigate the kidney and male genital tract. It is now the technique of choice in the initial diagnosis of certain renal diseases: primary renal vein thrombosis ...

Pediatric Abdominal Applications of Color Doppler Ultrasonography

Ultrasound Quarterly, 2002
Color Doppler ultrasonography (US) is a valuable imaging method because of the important information it provides with respect to organ perfusion, vessel patency, and tumor characterization. In addition, it is a noninvasive technique that does not use ionizing radiation. This review summarizes current applications of color Doppler US in the diagnosis of

Pancreas: imaging diagnosis with color/power Doppler ultrasonography, endoscopic ultrasonography, and intraductal ultrasonography

European Journal of Radiology, 2001
Recent advances of ultrasound imaging have made possible to depict various diseases and conditions of the pancreas. Color/power Doppler ultrasonography, endoscopic ultrasonography, and intraductal ultrasonography are feasible to show vascular abnormalities, differentiate the solid and cystic tumors, decide tumor extent, and help to perform ...

Retroperitoneal Fibrosis: Evaluation by Ultrasonography and Color Doppler Imaging

Urologia Internationalis, 2010
Delay in diagnosis is common in retroperitoneal fibrosis because of the nonspecific clinical presentation. Ultrasonography combined with color Doppler imaging is a rapid and practical method in the early diagnosis and during follow-up. We describe 3 cases with retroperitoneal fibrosis, emphasizing the ultrasonographic and color Doppler features of the ...

Ultrasonography and Color Doppler Imaging of Metastatic Pulmonary Choriocarcinoma

Chest, 1993
Chest ultrasound and color Doppler flow imaging were used to assess the pulmonary nodule of a 24-year-old pregnant woman with dyspnea and hemoptysis. The ultrasonogram showed multiple hypoechoic subpleural nodules. Color Doppler imaging of the nodules revealed characteristics of high vascularity and high blood flow.

Diagnosis of Rectal Varices via Color Doppler Ultrasonography

The American Journal of Gastroenterology, 2007
There has been no report on the hemodynamic evaluation of rectal varices by percutaneous color Doppler ultrasonography. Here, we report the usefulness of color Doppler ultrasonography for this purpose.Color Doppler ultrasonography was performed in 44 patients: 31 patients with portal hypertension, 7 with liver cirrhosis (LC) without portal hypertension,

Evaluation of Clitoral Blood Flow by Color Doppler Ultrasonography

Journal of Sex & Marital Therapy, 2000
The feasibility of reliably measuring clitoral blood flow using standard color Doppler ultrasonography was evaluated by two independent assessors in a sample of 40 pre- and post-menopausal women. High positive correlations with no significant mean differences between examiners were found for three major standard blood flow measures including maximum ...

Utility of Color Doppler Ultrasonography Predicting TIPS Dysfunction

The American Journal of Gastroenterology, 2005
Color Doppler ultrasonography (CDUS) has been proposed as an alternative to portal pressure gradient (PPG) measurement to detect transjugular intrahepatic portosystemic shunt (TIPS) dysfunction but with inconsistent results. This study aimed at developing and validating CDUS criteria to assess TIPS dysfunction.A total of 117 consecutive follow-up ...

Prediction of placenta accreta by ultrasonography and color doppler imaging

The Journal of Maternal-Fetal & Neonatal Medicine, 2010
To determine the accuracy of ultrasound and color flow Doppler to diagnose placenta accreta.Respectively, ultrasound images consistent with signs of placenta accreta (concomitant previa, numerous vascular lacunae, absent lower uterine segment between bladder-placenta, turbulent or complicated blood flow at the uteroplacental interface) were correlated ...

[The color Doppler ultrasonography in glaucoma diagnosis].

Ceska a slovenska oftalmologie : casopis Ceske oftalmologicke spolecnosti a Slovenske oftalmologicke spolecnosti, 2006
The insufficiency of the autoregulation at the optic nerve's head may cause the glaucoma optic neuropathy (GON). If the long-term stressing exists and an additional endurance arises, the autoregulation may fail and significant changes of the resistance index (RI) at the central retinal artery (CRA) and at the posterior ciliar artery (PCA) can be ...
