The transducer was held in the non-dominant hand of the operator, and placed below the costal margin in the short axis view (Figure 1).
This sonogram shows the needle trajectory from the lateral inferior side to the anterior superior side, towards the lateral anterior side of the vertebral body.

Upon identification of the three bony structures (the spinous process, articular process, and the vertebral body), the transducer was moved laterally and rotated anticlockwise until the diaphragm, erector spinae and psoas major muscles were identified (Figure 2).
The position of the needle tip is marked with 1 mL of contrast dye within both the anterior-posterior (AP) and lateral views by the C-arm.

After that, the US probe was removed and the position of the needle tip was marked with 1 mL of contrast dye within both the anterior-posterior (AP) and lateral views (Figure 3) by the C-arm.
