Renal Artery Stenosis Ultrasound. Aim Renal artery duplex ultrasonography (RDU) is an effective and noninvasive screening test in diagnosing renal artery stenosis The discordance of results in multiple RDU is common The discordance of results in multiple RDU is common Author Rong Zhu Zhonghui Xu Zhenhong Qi We Ye Jian Wang Jing Kong Jin Jin Jianchu LiCited by Publish Year 2018.

Background and purpose As a noninvasive side effectfree and costeffective method ultrasonography represents the method of choice for the diagnosis of renal artery stenosis Four different criteria in total including two direct criteria in peak systolic velocity (PSV) and renal aortic ratio (RAR) and two indirect criteria in resistance index (RI) and acceleration time (AT) for the measurement of relevant renal artery stenosis are described each demonstrating highly variable accuracy Author W Schäberle L Leyerer W Schierling K PfisterCited by Publish Year 2016.

Contrastenhanced ultrasound and renal artery stenosis Contrastenhanced ultrasound (CEUS) has recently added new possibilities to CDUS in the detection or RAS as it improves visualization of the main RAs and accessory vessels and reduces the number of equivocal examinations (Fig 9) US contrast agent increases the intensity of the Doppler signals thus producing a more rapid and complete visualization of the RAs Author A Granata F Fiorini S Andrulli F Logias M Gallieni G Romano E Sicurezza CE FioreCited by Publish Year 2009.

The renal artery is difficult to visualize in the two planes necessary for appropriate grading (only oblique planes possible) Renal artery branch stenosis in particular can be challenging to visualize Ultrasound PSV grading is generally compared with angiography solely in an anteroposterior plane Author W Schäberle L Leyerer W Schierling K PfisterCited by Publish Year 2016.
