Activity assessment in morphea using color Doppler ultrasound [PDF]

Journal of the American Academy of Dermatology, 2011
Background: Morphea (circumcripted cutaneous scleroderma) can be difficult to assess for lesion activity. Because variable-frequency ultrasound with color Doppler provides details of skin morphology and function, it may help in the categorization of ...

Physical Principles of Doppler and Color Doppler Ultrasound

2021
Doppler 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, 2004
Varicocele, 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 ...

Color Doppler ultrasound of the genitourinary tract

Current Opinion in Urology, 1992
This 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 ...

[Doppler ultrasound study of breast tumors using color Doppler ultrasound, duplex ultrasound and the CW Doppler ultrasound].

Zentralblatt fur Gynakologie, 1992
The preoperative examinations by doppler-sonography of 83 patients with tumors of the breast are presented. The examinations are done with newest technique: duplex-sonography in slow-flow-technique (AI 3200, Dornier); colour-sonography in MEM-technique (AI 5200, Dornier) and synchronical colour-doppler++ (Quantum 2000, Siemens) and CW-doppler ...

Color Doppler ultrasound imaging of theeye and orbit

Survey of Ophthalmology, 1996
Color Doppler imaging is a non-invasive ultrasound procedure which permits simultaneous gray scale imaging of structure and color-coded imaging of blood velocity. This improved technique allows the user to identify even very small blood vessels, such as those supplying the eye, from which measures of blood velocity and vascular resistance can be ...

Ultrasound and Color Doppler Ultrasound of Liver Metastases

1999
In western countries metastases are the most common cause of malignant focal liver lesions. Metastases are 18–20 times more common than primary malignant tumors. Sixty percent of patients with newly diagnosed solid tumors (excluding skin cancer other than melanoma) have clinically evident or microscopic metastases, when the primary tumor is diagnosed ...
