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 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 کاملReal-time and power Doppler imaging of fetal adrenal hemorrhage.
Adrenal hemorrhages are not uncommon in newborns, but they may occur before birth. The incidence of adrenal hemorrhages based on extensive necropsy has been estimated as about 1.7 per 1000 births. With the increasing use of ultrasonography, prenatal recognition of fetal adrenal hemorrhages has become more common in recent years. We report an echogenic abdominal mass, which was found at 36 weeks...
