Breast masses: Color Doppler, power Doppler, and spectral analysis findings

Journal of Clinical Ultrasound, 1998
To determine the diagnostic efficacy of power Doppler sonography (PDS) with spectral analysis for breast diseases, we retrospectively compared PDS and color Doppler sonography (CDS) in patients with breast lesions.One hundred thirty-eight women with palpable breast lesions were examined with PDS (65 women) and/or CDS (73 women).

Power Doppler in breast tumours: a comparison with conventional colour doppler imaging

European Journal of Ultrasound, 1998
Tumour vascularity can be assessed in-vivo using Doppler ultrasound. The purpose of this study was to determine whether Power Doppler imaging (PDI) better differentiates benign from malignant breast masses than conventional colour doppler imaging (CDI) on the basis of assessment of tumour vascularity.One-hundred women with solid breast lumps (51 ...

Measurement of the Doppler Power of Flowing Blood Using Ultrasound Doppler Devices

Ultrasound in Medicine & Biology, 2015
Measurement of the Doppler power of signals backscattered from flowing blood (henceforth referred to as the Doppler power of flowing blood) and the echogenicity of flowing blood have been used widely to assess the degree of red blood cell (RBC) aggregation for more than 20 y. Many studies have used Doppler flowmeters based on an analogue circuit design

3D POWER DOPPLER IN OBSTETRICS

Fetal and Maternal Medicine Review, 2011
Flow is defined as the amount of fluid, ordinarily blood, passing per unit time (usually per minute). Perfusion is defined as the volume of blood flowing through a mass of tissue per unit time. The standard measure of perfusion is millilitres of fluid per second per 100 g of tissue (or 100 ml in volume) i.e.

[The significance of the Doppler techniques -- "color Doppler" and "power Doppler" -- in the diagnostic ultrasonography of the eyeball].

Polski merkuriusz lekarski : organ Polskiego Towarzystwa Lekarskiego, 1999
The eyeball is perfectly suited for ultrasound examination due to its location and structure. The ultrasound examination including the "color Doppler" and "power Doppler" option was performed in 59 patients. Ophthalmologists requested ultrasound examination in those patients mainly in order to confirm and differentiate retinal ablation or because of ...
