Figure 1: Ipsilateral cervical changes in anatomic neutral and right torsion. (a) Descending trapezius: As the neck rotates from the neutral to right torsion, the cranial descending trapezius shifts medially and increases in thickness. Rotation also obscures the bony landmark of the cervical spine. (b) Caudal trapezius: In contrast, the caudal trapezius does not change significantly upon rotation. (c) Anterior and Middle Scalenes: anterior and middle scalenes move more anteriorly when the neck rotates from neutral to torsion. The brachial plexus, which appears as a “traffic light” in neutral position (displaying three circles of the superior, middle, and inferior portions of the brachial plexus in cross section) becomes less recognizable and distorted with torsional stress due to the obliquity and anisotropy. (d) Right Splenius Capitis and Cervicis Muscles: The right splenius capitis and splenius cervicis flatten. The sternocleidomastoid slides over the splenius capitis in the cine loop. (e) Right Levator Scapulae: The right levator scapulae increases in cross-sectional area when in torsion
