1 A–C, Anteroposterior (A), oblique (B), and lateral (C) radiographs after thoracic interlaminar epidural injection of contrast material reveal opacification of the lower thoracic epidural space dorsally before injection of steroid and local anesthetic. A–C, Anteroposterior (A), oblique (B), and lateral (C) radiographs after thoracic interlaminar epidural injection of contrast material reveal opacification of the lower thoracic epidural space dorsally before injection of steroid and local anesthetic. The Whitacre needle tip is in the midline within the posterior epidural space. Contrast material is seen extending along the proximal thoracic nerve sheaths (arrows)‏ Blake A. Johnson et al.
