Fig. 4From: Morphological characteristics of subaxial cervical pedicles and surrounding critical structures in patients with vertebral artery dominance - an anatomical study based on computed tomographic imagingSeries CT images of C4 show that the patient with VAD exhibit smaller POW on the dominant side than that on the non-dominant side (A: 4.43 mm VS 5.41 mm; B: 4.92 mm VS 5.73 mm; C: 4.42 mm VS 5.34 mm; Averaged POW: 4.59 mm VS 5.49 mm). VAD, vertebral artery dominance; POW, the distance between the lateral cortical border and medial border at the most stenotic area of the pedicleBack to article page
