A doppler ultrasound clutter phantom
Ultrasound in Medicine & Biology, 1996We describe two variations of a phantom designed to evaluate the wall filters implemented on colour and spectral Doppler instruments. Both variations use an acoustic beam splitter to place the same Doppler sample volume within a motor-driven clutter belt and a flow source, which is either a second belt (dual-belt phantom) or a vascular phantom (belt ...

Doppler Ultrasound in Pregnancies with Hypertension
Australian and New Zealand Journal of Obstetrics and Gynaecology, 2008Doppler studies of the arcuate and umbilical arteries were performed longitudinally commencing at 24 weeks or less, in 29 pregnant women with chronic hypertension. The hypothesis was that pregnant women with chronic hypertension who develop superimposed gestational proteinuric hypertension and/or deliver small for gestational age babies are those who ...

Doppler Ultrasound of the Renal Vasculature
Journal of Ultrasound in MedicineUltrasound is the first‐line imaging modality used in patients with suspected renovascular disease. Common indications include renovascular hypertension and unexplained renal dysfunction. We review the ultrasound imaging findings of various pathologies involving the renal vessels, including the renal arteries (atherosclerotic stenosis, fibromuscular ...

Routine Doppler ultrasound in pregnancy
2000Doppler ultrasound study of umbilical artery waveforms helps identify the compromised fetus in 'high risk' pregnancies and, therefore, deserves assessment as a screening test in 'low risk' pregnancies. One of the main aims of routine antenatal care is to identify the 'at risk' fetus in order to apply clinical interventions which could result in reduced

Doppler ultrasound - basics revisited
British Journal of Nursing, 2006Palpation of pedal pulses alone is known to be an unreliable indicator for the presence of arterial disease. Using portable Doppler ultrasound to measure the resting ankle brachial pressure index is superior to palpation of peripheral pulses as an assessment of the adequacy of the arterial supply in the lower limb. Revisiting basics, this article aims
