Positioning guided by the orientation of the ultrasound probe. (a-b) Sagittal CT image showing the posterior aspect of the scanned vertebra is not parallel to the edge of the bed under the standard lateral decubitus position. Note that a cephalad (a) or caudad (b) angulation of the probe is commonly required to obtain the optimal visualization of the anterior complex in patients with scoliosis and hyperlordosis. (c-d) Sagittal CT image demonstrating modified position with the posterior aspect of the scanned vertebral body adjusted to align with the edge of the bed, allowing for a perpendicularly (to the edge of the bed) placed probe
