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 ...

CONTRAST-ENHANCED COLOR DOPPLER ULTRASONOGRAPHY IN SUSPECTED PARATHYROID LESIONS
Acta Radiologica, 2000Purpose: To assess the usefulness of US contrast media in the evaluation of patients with primary hyperparathyroidism, with a nodule showing US features of a primary parathyroid lesion but lacking the color Doppler US appearance of a parathyroid mass. Material and Methods: Thirteen patients (7 female, 6 male; age range 51-79 years) were examined with

Testicular Color Doppler Ultrasonography in Barki Rams
Alexandria Journal of Veterinary Sciences, 2019The aim of the present study was to determine the blood flow dynamics of the testes of pre and post pubertal clinically normal Barki rams. Rams (n=8) were divided into two equal groups according to age. The first group was pre-pubertal rams (aged 4-6 months) and the second group was post pubertal sexually mature rams (aged 18-24 months).

Gastrointestinal inflammation in children: color Doppler ultrasonography.
Journal of Ultrasound in Medicine, 1994We conducted this study to determine if color Doppler ultrasonography can identify increased vascularity associated with gastrointestinal inflammatory conditions and to determine if specific diagnoses can be established based on flow patterns. Twenty-five children with acute right lower quadrant pain and discharge diagnoses of inflammatory bowel ...

Color Doppler ultrasonography of the eye and orbit
Current Opinion in ophthalmology, 1993Color Doppler imaging is the recent development in ultrasonography that allows simultaneous two-dimensional structural imaging in Doppler evaluation of blood flow. With this technique, it is possible for the first time to indirectly display the fine orbital vessels such as the ophthalmic artery and its branches, the central retinal artery, the ...

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 ...

[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 ...

Color Doppler application in laparoscopic intraoperative ultrasonography.
Surgical technology international, 2012During the past decade, several investigators reported effective application of intraoperative ultrasonography as a new diagnostic modality in surgery. Intraoperative ultrasonography has been successfully applied in the screening of the biliary tract and in the examination of the liver, pancreas, urinary tract, and endocrine organs.
