30 gru 2019 · The color flow image helps to identify vessels and the blood flow abnormalities caused by arterial lesions ( Figs. 15.1 and 15.2). The ability to visualize blood flow abnormalities throughout a vessel improves the precision of pulsed Doppler sample volume placement for obtaining spectral waveforms.

31 paź 2019 · This small-scale study provides preliminary evidence that by factoring PI values into volume flow calculations, one can explain a wide range of normal volume flow values in the lower limb arteries and other conflicting phenomena in previous Doppler ultrasound and MR angiography studies.
15 lip 2020 · Abstract. This expert consensus statement on the interpretation of peripheral arterial and venous spectral Doppler waveforms was jointly commissioned by the Society for Vascular Medicine (SVM) and the Society for Vascular Ultrasound (SVU).
20 lip 2023 · In cases of femoral artery cannulation, the external iliac artery velocity spectra may show increased PSVs, and altered flow signal proximal to the AVF. While evaluating peripheral aneurysms, their location and widest diameter of the aneurysm should be documented on grayscale images.
1 gru 1996 · The arterial narrowing or obstruction that occurs as a result of the atherosclerotic process reduces blood flow to the lower limb during exercise or at rest. A spectrum of symptoms results, the severity of which depends on the extent of the involvement and the available collateral circulation.
26 lut 2021 · A normal color flow duplex ultrasound and triphasic waveforms at the common femoral artery (CFA) indicate normal aortoiliac flow since the aorta and iliac arteries are proximal to the CFA.
24 kwi 2024 · Vascular imaging confirms a diagnosis of peripheral artery disease (PAD), assesses the severity and extent of disease, and is used to plan and guide revascularization (open surgical or endovascular).
