The diagnosis was confirmed by angiography. The renal vascular lesion in neurofibromatosis usually affects the proximal segment of the artery, which is the part most optimally visualized by ultrasound. We suggest that Doppler ultrasound of the renal arteries may be a useful technique in the ...
Upon reaching the renal hilum, the main renal arteries divide into anterior and posterior segmental arteries. These further divide to feed the multiple segments of the kidney. The segmental arteries, in turn, give rise to the interlobar arteries which course alongside the renal pyramids toward the...
Ex vivoμCT can also produce detailed images of the dense renal microvasculature in rodents24,25,26,27,28,29. Therefore, our study aimed to directly compare the vascular anatomy shown in two in vivo 2D SRUS images of a Sprague–Dawley rat kidney with ex vivoμCT of the same kidney. For...
The celiac artery remains a low resistance vessel The SMA becomes low resistance, because now it needs more blood for digestion If the SMA does not change dramatically after eating, there is a stenosis/occlusion Low resistance abdominal arteries renal celiac hepatic High resistance abdominal ar...
Renal artery stenosis: the use of duplex ultrasound as a screening technique. Over an 18-month period, 44 patients with hypertension were referred for evaluation of the renal arteries by duplex Doppler ultrasound. Those patients refe... Robertson,Murphy,P A,... - 《British Journal of Radiology...

The spectrum of the blood flow velocity in renal arteries and their branches is a low resistance one. The following parameters are used to evaluate normal renal arteries and to identify the narrowed ones: Vmax, Vmin, RAR, AT, AI, RI and PI. 展开 ...
Chronic kidney disease can occur if plaque builds up in the renal arteries. These arteries supply oxygen-rich blood to your kidneys.Over time, chronic kidney disease causes a slow loss of kidney function. The main function of the kidneys is to remove waste and extra water from the body. ...
This provides us with an excellent tool for delineating tissues with perfusion differences and for following the dynamic phases of contrast enhancement, in both large vessels and the microcirculation in parenchymatous organs. For vascular applications, CEUS improves detection of the renal arteries as ...
