Kidney biopsy and power Doppler imaging.
BACKGROUND Practically, all complications of kidney biopsy are connected with hemorrhage. In the last years, the use of color Doppler sonography in monitoring kidney biopsies was being described, later the possibility of using power Doppler (PD) in performing kidney biopsies was presented. PD depicts the amplitude, or power, of Doppler signals rather than the frequency shift. This allows detect...
متن کاملThe effectiveness of power Doppler vocal fremitus imaging in the diagnosis of breast hamartoma.
OBJECTIVES To evaluate the usefulness of power Doppler vocal fremitus (PDVF) breast sonography for differentiation of hamartomas from other breast (malign or benign) masses. MATERIAL AND METHODS Two hundred and six breast masses in 180 women were evaluated. The breast lesions were scanned first by mammography (MG), then by ultrasonography (US) with PDVF imaging. Finally, biopsy was performed ...
متن کاملThe difference between Colour Doppler Velocity Imaging and Power Doppler Imaging.
The Doppler effect, which occurs on the reflection of ultrasound from moving blood or tissue, is observed as a shift in frequency of the reflected ultrasound from that of the incident ultrasound. This Doppler shift has been widely used in clinical practice as a means of measuring blood velocity. Two types of Doppler Imaging are often discussed as facilities on ultrasonic scanners, namely Colour...
متن کاملI-44: Color Doppler Imaging in Impotence
Sexual impotent is very common entity and define as inability to induce or maintaining penile erection during sexual intercourse. Studies reveals about 10% of men aged 40-70 years have complete, 17% have mild and 25% have moderate amount of erectile dysfunction. The sexual impotence has different etiology including psychogenic, neurogenic, arteriogenic and venogenic causes. Current studies reve...
متن کاملSignal losses with real-time three-dimensional power Doppler imaging.
Power Doppler imaging (PDI) has been shown to be influenced by the wall filter when assessing arterial stenoses. Real-time 3-D Doppler imaging may likely become a widespread practice in the near future, but how the wall filter could affect PDI during the cardiac cycle has not been investigated. The objective of the study was to demonstrate that the wall filter may produce unexpected major signa...
