4.2.1\ Scanning Method

The patient should be on an empty stomach for 8–12 h, and should be in a supine position. The probe is placed transversely at the subxyphoid level.

4.2.2\ Section Structure

Transverse section of the SMA and the accompanying SMV on the right; the transverse section of the IVC and Ao lies behind.

4.2.3\ Measurement Method and Normal Value

The diameters of the SMA and SMV are measured.

4.2.4\ Clinical Application Value

This section can be used to orient the SMA and facilitate a long-axis view of it.
