Fig. 9.18  Coronal section at the lumbar region: longitudinal view of the renal artery

5.2.1\ Scanning Method

The patient should be in a lateral position. The probe is placed vertically on the anterior, middle, or posterior axillary line, according to the body type. The coronal section of the kidney is used as the echo window.

5.2.2\ Section Structure

Coronal section of the kidney, renal artery, Ao, renal vein, intrarenal artery branches.

5.2.3\ Measurement Method and Normal Value

The method is the same as that shown above.

5.2.4\ Clinical Application Value

On this section, the echo–flow angle is usually smaller than 60° so the measurement of PSV is more reliable. The renal vein can also be evaluated on this section; the typical features of renal vein thrombosis include enlargement of the renal vein, a hypoechoic region in the lumen, and absence of the blood flow signal.
