Fig 1 The baseline US technique. (A) Lower level of an SIJ, displayed by a short-axis sonogram. The tip of the needle (white arrow) can be visualized under the perpendicular US beam in the hypoechoic cleft of the SIJ dorsal margin (arrowhead). The white arrow indicates the perpendicular needle positioning. The white star indicates posterior sacral foramen 2. (B) Color Doppler sonogram shows vascularization (arrow) within the posterior portion of SIJ.
