26 gru 2015 · A, Color aliasing (short arrow) is seen in the proximal segment (arrowhead) of the right renal artery. B, Pulse wave Doppler image of the proximal segment of main renal artery reveals a peak systolic velocity of 452 cm/sec. C, Accessory renal artery is seen arising from the aorta (short arrow).
21 lis 2016 · Renal artery doppler is a powerful tool for the diagnosis of Renal Artery Stenosis (RAS). One of the more involved exams in the sonographers arsenal, learning the proper anatomy and techniques can make the process a challenging yet pleasurable one.
Blood enters the kidney via the renal artery which divides dichotomously into segmental arteries and branch progressively into interlobar arteries. Arcuate arteries, separating the...

2 sty 2020 · Renal artery stenosis. (A) Color Doppler image shows segmental narrowing of the right renal artery with color aliasing in the stenotic region ( arrow ). (B) Elevated peak systolic velocities ( PS ) measuring 305 cm/s are present in the stenosis. (C) Spectral Doppler sample through the mid abdominal aorta demonstrates a peak systolic velocity of ...
3 maj 2021 · In this article, we review a range of pathologic entities that can affect the RAs, including hemorrhage and pseudoaneurysm formation, arteriopathies such as atherosclerotic RA stenosis (RAS), fibromuscular dysplasia (FMD), vasculitis and RA aneurysm (RAA), angiomyolipoma (AML), dissection, and embolism.
30 lip 2021 · Complete renal vascular Doppler assessment involves determining the patency and waveform of the main renal artery and vein; the waveform of the arcuate and interlobar arteries in the upper, interpolar, and lower pole regions; and their associated resistive index (RI).
