Trans-sellar Color Doppler Ultrasonography during Transsphenoidal Surgery

Neurosurgery, 1998
To improve the safety and efficacy of transsphenoidal pituitary adenoma surgery, we investigated transsphenoidal intraoperative color Doppler ultrasonography using a biplane transducer system.We studied 23 patients with pituitary adenomas (18 patients with macroadenomas and 5 patients with microadenomas) who underwent transsphenoidal surgery.

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

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,

[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 ...

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 ...

Doppler and color Doppler ultrasonography in renal transplants: Chronic rejection

Journal of Clinical Ultrasound, 1992
AbstractAlthough 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, 2000
Purpose: 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, 2019
The 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, 1994
We 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, 1993
Color 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 ...
