Thyroid nodules: evaluation with color Doppler ultrasonography

Journal of Ultrasound in Medicine, 1993
Forty-seven patients with thyroid nodules (13 papillary carcinomas, 14 adenomas, and 20 adenomatous goiters) underwent color Doppler sonography with a 7.5 MHz transducer. Perinodular or intranodular color flow signals were depicted in 10 of 13 papillary carcinomas, in 10 of 14 follicular adenomas, and in 14 of 20 adenomatous goiters.

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 ...

Application of color Doppler ultrasonography to ulcerative colitis

Journal of Medical Ultrasonics, 2003
We used color Doppler ultrasonography (US) to evaluate bowel wall thickening in ulcerative colitis and to determine the value of this modality in this application. Twelve patients (6 men and 6 women) with ulcerative colitis underwent both gray-scale and color Doppler US.

Errors in Color Doppler Ultrasonography

2012
Artifacts are encountered daily in routine clinical sonography. They may be observed in B-mode gray-scale imaging, spectral pulsed Doppler imaging, and color Doppler imaging. In the context of imaging, the word “artifact” is taken to mean components of the image that are generated in the imaging process but which are not properly indicative of the ...

Prenatal diagnosis of sirenomelus with color Doppler ultrasonography

American Journal of Obstetrics and Gynecology, 1994
Sirenomelus is an invariably lethal congenital anomaly characterized by complete or nearly complete fusion of the lower extremities that occurs in 1 of 60,000 births. In about 50% of cases this condition cannot be diagnosed prenatally because of the associated oligohydramnios that precludes a detailed examination of the fetus.

Color Doppler Ultrasonography in the Evaluation of the Acute Scrotum

Journal of Urology, 1992
Color Doppler ultrasonography was used to assess 20 patients with the acute onset of scrotal pain. Patients were categorized into 3 groups according to the initial clinical impression of the examining physician: ischemia, inflammation or trauma. Color Doppler ultrasonography correctly predicted the need for surgery in 8 of 9 operated patients (89%) and

Color Doppler ultrasonography in pediatric intussusception.

Journal of Ultrasound in Medicine, 1994
CDU was used in 11 children with intussusception. Demonstration of vascular images within the "pseudokidney" mass was possible in none of 11 cases. Of them, eight could be treated by hydrostatic reduction. In the remaining case, marked edema of the bowel wall did not allow reduction, and surgery had to be performed: no necrosis was observed in the ...

[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 ...
