  • Thoracic Vertebral Levels
    • T1: Located at the base of the neck, just below the prominent C7 vertebra (“vertebra prominens”).
    • T3: Roughly at the level of the medial end of the scapular spine.
      • T3 is the vertebra is considered the cervicothoracic inflection point, the point where cervical lordosis becomes thoracic kyphosis
    • T7: Lies opposite the inferior angle of the scapula when the arm is held by the side.
      • Drawing a line from one scapular tip to another best approximates the T7 lamina when radiographs cannot be used due to patient size or x-ray quality.
    • T12: Found just above the lower margin of the rib cage; demarcates the thoracolumbar junction.
