Figure 2

Ultrasound identification of the seventh cervical vertebra (C7) during the UG-MSN and UG-DN techniques. (a) Three-dimensional computed tomography reconstruction of the cervical vertebrae. The white arrow indicates C7. (b) Conventional computed tomography scanning of C7. (A) The posterior tubercle of the transverse process of C7. (c) Ultrasound imaging of C7. The dotted line represents the posterior tubercle of the transverse process of C7. The letters (A)–(F) indicate, respectively, the medial scalenus muscle, posterior tubercle, brachial plexus, sternocleidomastoideus muscle, anterior scalenus muscle, and cervical artery. Post.: posterior position of patients. Ant.: anterior position of patients.
