With the patient in a supine position you can approach the renal vessels just below the epigastrium
In an axial plane you will view the renal arteries in a longitudinal orientation
In this approach you will have to angle your probe or tilt it in order to get good angles of insonation. This helps us spot any bottlenecks—like narrowing or blockages—that could be causing trouble Hemodynamic changes in the renal artery and kidney are evaluated with color and spectral doppler us What is a renal vascular ultrasound & doppler
