Color Doppler Ultrasound Assessment of Activity in Keloids
Dermatologic Surgery, 2017BACKGROUND The assessment of activity in keloids may be critical for defining their management. There is a lack of clinical scorings designed for the evaluation of keloids and biopsies may be contraindicated. OBJECTIVE To assess the sonographic activity of keloids in comparison with

Color doppler ultrasound of pulmonary consolidation
European Journal of Ultrasound: Official Journal of the European Federation of Societies for Ultrasound in Medicine and Biology, 1996Abstract Color Doppler ultrasound (US) is a very powerful imaging tool that can simultaneously display blood flow information and Doppler spectral analysis. This imaging modality, for the first time, provides an opporturnity to assess pulmonary blood flow and perfusion noninvasively. Color Doppler US has many potential applications in diseases of the

Evaluation of Stone Features That Cause the Color Doppler Ultrasound Twinkling Artifact.
Ultrasound in Medicine and Biology, 2021The color Doppler ultrasound twinkling artifact is a rapid color shift that appears on 43%-96% of kidney stones. Surface microbubbles on kidney stones are theorized to cause twinkling as exposure to elevated static pressures of 0.41-1.13 MPa ...

Color Doppler Ultrasound in Portal Hypertension
Journal of ultrasound in medicine, 2020Portal hypertension is one of the most important causes of morbidity and mortality in cirrhotic patients. A color Doppler evaluation of the left gastric vein (LGV) has proven utility in the prediction of esophageal varices and variceal bleeding in ...

Color Doppler ultrasound in ovarian fibrosarcoma
Gynecologic Oncology, 2004Primary ovarian fibrosarcoma is a very rare tumor. Its Doppler waveform characteristics have not been described before.A 35-year-old woman presented with a 5-cm solid ovarian mass. Intratumoral artery resistance index (RI) and pulsatility index (PI) were very low (0.19 and 0.21, respectively).

Physical Principles of Doppler and Color Doppler Ultrasound
2021Doppler ultrasound is based on application of the Doppler effect, also called the Doppler shift. In medicine the ultrasound wave is reflected off the moving objects which are erythrocytes in blood vessels. The following types of applications of the Doppler shift in diagnostic imaging are distinguished: Spectral Doppler, including Continuous wave ...

Color Doppler ultrasound investigation of varicocele
World Journal of Urology, 2004Varicocele, whose association with male infertility has been clearly documented in the literature, is a common finding in adolescents and adult men, being diagnosed in 20-40% of infertile patients. A correct and early diagnosis of this affliction is of great importance because, in most cases, a timely correction, usually performed using percutaneous ...

Using Ultrasound Color Doppler Twinkling to Identify Biopsy Markers in the Breast and Axilla.
Ultrasound in Medicine and Biology, 2021In breast radiology, ultrasound detection of biopsy markers or clips for localization purposes is often challenging, especially in the axilla. The purpose of this research was to test the hypothesis that the surface roughness of biopsy clips would elicit

Color Doppler ultrasound of the genitourinary tract
Current Opinion in Urology, 1992This paper discusses the role of color Doppler ultrasonography (CDU) as it applies to the genitourinary tract. CDU is beneficial in evaluating both the native and allograft kidney in the diagnosis of renal arterial and venous stenosis, arteriovenous fistulas, pseudoaneurysms, arterial and venous thrombosis, and in the characterization and staging of ...
