Retroperitoneal Fibrosis: Evaluation by Ultrasonography and Color Doppler Imaging
Urologia Internationalis, 2010Delay 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 ...

Doppler and color Doppler ultrasonography in renal transplants: Chronic rejection
Journal of Clinical Ultrasound, 1992AbstractAlthough Doppler and color Doppler ultrasonography has been used extensively to examine acute changes in renal allograft function, there have been few reports on the role of Doppler ultrasonography in the assessment of chronic rejection. In those studies that have addressed chronic rejection, there is agreement that changes in renal function ...

Ultrasonography and Color Doppler Imaging of Metastatic Pulmonary Choriocarcinoma
Chest, 1993Chest 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, 2007There 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, 2000The 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, 2005Color 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, 2010To 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, 2006The 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 ...

The purpose of this study was to assess the usefulness of color and power Doppler imaging in thyroid nodules. The following 4 items were compared between malignant thyroid nodules (34 cases) and benign nodules (51 cases): 1) vascularity; 2) distribution of tumor vessels (none, marginal, peripheral, central); 3) nature of tumor vessels (tortuosity ...
