The use of two-dimensional Doppler sonography (color Doppler) in the diagnosis of hydranencephaly

Child's Nervous System, 1990
Hydranencephaly, first described by Cruveilhier, may be defined as a rare condition in which the cerebral hemispheres are replaced by membranous sacs filled with cerebrospinal fluid. Cerebral angiography is especially useful in differentiating hydranencephaly and severe hydrocephalus, massive subdural hygromas and alobar holoprosencephaly, but it is no

Is Color Doppler Ultrasound Useful in Diagnosing Ovarian Cancer?

Clinical Obstetrics and Gynecology, 1999
In summary, the emergence of CDUS presented an interesting new technical approach to the study of neovascularization in ovarian cancers. Techniques for CDUS are technically difficult and plagued with artifacts making correct interpretation difficult. Measures of blood flow (such as the resistive index) overlap significantly between ovarian cancers and ...

Color modulation of Doppler spectra with the use of a personal computer

Computers in Biology and Medicine, 1991
This paper describes a method for the use of a personal computer in developing color modulated spectral maps of blood flow echoes from a Doppler flowmeter. The acoustical signal from a Doppler flowmeter is digitized and transformed into the frequency domain with a fast Fourier technique with the use of an Apple IIe microcomputer in conjunction with a ...

Fallopian tube patency using color Doppler

International Journal of Gynecology & Obstetrics, 1993
To evaluate a new test for tubal patency using color Doppler ultrasonography in infertile women.Between October 1991 and March 1992 results of our new technique were compared with those of hysterosalpingography (HSG) and laparoscopy in 27 cases. The new technique of evaluating tubal patency using color Doppler has been described in detail.There was 92 ...

Doppler catheter tip localization using color enhancement

Catheterization and Cardiovascular Diagnosis, 1994
AbstractThe objective of this research was to determine if the ultrasound emissions of the Doppler catheter can be used to locate its position in 3 dimensions by conventional echocardiography. A Doppler catheter has previously been shown to permit nonfluoroscopic retrograde catheterization of the aortic root and left ventricular chamber by using ...

Imaging Priapism: The Diagnostic Role of Color Doppler US

2007
As described in Chapter 9, priapism is an uncommon medical condition defined as persistent tumescence or erection not associated with sexual desire or stimulation (Pautler and Brock 2001). Different pathophysiologies have been described. Low-flow or ischemic priapism is characterized by complete painful erection secondary to inadequate venous outflow ...

Occult breast carcinoma — Use of color Doppler in localization

Breast Cancer Research and Treatment, 1996
Occult breast carcinoma presenting with axillary metastases is a difficult clinical problem. Mammography is recommended as the diagnostic tool for detecting breast masses, but is very insensitive. In two consecutive patients with nonpalpable carcinoma of the breast, the detection of breast lesions was made by color Doppler sonography.

Acute Kidney Injury: Color Doppler US

2021
Acute renal failure (ARF) is characterized by a rapid reduction in glomerular filtration rate with secondary retention of slag (hyperazotemia, hypercreatininemia, alteration of the electrolyte balance, acidosis) due to organic or functional causes.
