Doppler and color Doppler imaging in acute transplant failure
Journal of Clinical Ultrasound, 1992AbstractMost renal transplants are lost by rejection. A method is required to identify and discriminate between this and acute tubular necrosis and cyclosporin toxicity. The sonogram of the normal renal transplant is characteristic. Early Doppler studies measuring a rise in vascular impedance in acute rejection showed a high sensitivity and specificity.

Doppler echocardiography. II. Color Doppler imaging.
The Veterinary clinics of North America. Small animal practice, 1999Color Doppler imaging (CDI) is a sophisticated form of ultrasound technology that overlays blood flow and velocity information onto a B-mode, two-dimensional, gray-scale image. This imaging technique--also called color Doppler echocardiography, color-coded Doppler, Doppler color-flow imaging, and color-flow imaging--is a type of pulsed-wave Doppler ...

Color flow Doppler: Imaging the upper extremity
The Journal of Hand Surgery, 1993Dynamic values of key vessel diameter, blood velocity, and flow rate in the upper extremity were obtained in 20 healthy volunteers by means of color flow Doppler imaging with a 7.5 MHz transducer. Recordings were made of the brachial, radial, posterior radial recurrent, ulnar, and digital arteries.

Color doppler imaging for vocal cord palsy
Head & Neck, 1995AbstractBackground. Conventional techniques of laryngoscopy for vocal cord palsy can sometimes be difficult or impossible to perform, and B‐mode real‐time ultrasonography has been previously reported by the authors to be helpful in these situations. In some cases, however, B‐mode ultrasonography can be inconclusive.

Color Doppler imaging of focal splenic masses
European Journal of Radiology, 1994We report the sonographic findings in 43 patients with focal splenic masses. A differential diagnosis of splenic tumors was attempted on the basis of echotexture, size, vascularity and patterns of blood flow within and around tumors on color Doppler sonography. Using the surrounding splenic tissue as an in vivo reference, markedly hypervascular (n = 3),

Color Doppler Imaging of Normal Orbital Vasculature
Ophthalmology, 1995Color Doppler imaging has become a useful adjunctive tool in diagnosing ophthalmic vascular disease. However, a paucity of information exists regarding normal values. This investigation was conducted to generate a database of normal retrobulbar circulatory parameters.The authors prospectively studied the retrobulbar hemodynamic parameters of 53 normal ...

Operative color Doppler imaging for general surgery
Journal of Ultrasound in Medicine, 1993Operative CDI was performed during 125 general surgical operations (53 hepatic, 25 biliary, 24 pancreatic, 7 esophagogastric, 10 pulmonary, 3 kidney transplant, and 3 soft tissue operations). Operative CDI provided beneficial information in 108 of 125 operations (86.4%).

Color-Doppler Imaging in Acute Scrotal Disorders
Urologia Internationalis, 1993Eighteen patients who referred to our hospital with acute scrotal pain and swelling were evaluated with color-Doppler imaging (CDI) after the initial clinical examinations. Five of these subjects were considered to have testicular torsion as diagnosed with CDI. These diagnoses were surgically confirmed, and appropriate treatments were performed.

1994
Color Doppler flow imaging is based on pulsed wave Doppler technology. Blood flow velocity can be measured by analyzing the velocity of the red blood cells in a small area, called a sample volume, along a scan line superimposed on the two-dimensional echocardiogram.

Basics of Color Doppler Imaging
1991Color Doppler flow imaging (CDFI) is a relatively new ultrasound method to assess vascular function and morphology. Primarily introduced to echocardiography in the early 1980s [1–3], it has been more recently applied in vascular diagnostics [4]. The objective of this chapter is to describe the basic concepts applied in CDFI.
