Hysterosalpingography with color Doppler ultrasonography
American Journal of Obstetrics and Gynecology, 1991To assess the accuracy of the diagnosis of tubal occlusion with the use of color Doppler flow ultrasonography and hysterosalpingography, 129 infertile women were studied. All 129 women had the procedure performed with an ATL Ultramark 9 (Advanced Technology Laboratories, Bothel, Wash.) color Doppler ultrasonography machine. Eighty-five of the 129 women

Investigation of placental circulations by color Doppler ultrasonography
American Journal of Obstetrics and Gynecology, 1991The placental circulations of 25 normal and five complicated pregnancies were studied by color Doppler ultrasonography. Flow velocity waveforms were obtained in all 30 pregnancies and could discriminate between fetal and maternal intraplacental blood flow.

Color doppler ultrasonography of soft-tissue masses
Acta Radiologica, 1998Purpose: To evaluate the capability of color Doppler ultrasonography to differentiate between benign and malignant soft-tissue tumors. Material and Methods: We reviewed the ultrasonographic (US) and color Doppler (CD) findings in 46 consecutive patients with a palpable periskeletal mass.

Color Doppler Ultrasonography in Patients with Subacute Thyroiditis
Thyroid, 1999We studied the utility of color Doppler ultrasonography in patients with subacute thyroiditis. Eighteen patients with subacute thyroiditis (SAT) with painful goiter and thyrotoxicosis underwent color Doppler ultrasonography during the acute and recovery stages of the disease.

Thyroid nodules: evaluation with color Doppler ultrasonography
Journal of Ultrasound in Medicine, 1993Forty-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.

Application of color Doppler ultrasonography to ulcerative colitis
Journal of Medical Ultrasonics, 2003We 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.

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 ...

Prenatal diagnosis of sirenomelus with color Doppler ultrasonography
American Journal of Obstetrics and Gynecology, 1994Sirenomelus 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.

Errors in Color Doppler Ultrasonography
2012Artifacts 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 ...

Color Doppler Ultrasonography in the Evaluation of the Acute Scrotum
Journal of Urology, 1992Color 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
