The osseous framework of the thoracic spine makes up for a narrow acoustic window with limited ultrasound visibility of the spinal canal and neuraxial structures.1,2 Ultrasound visibility of the thoracic spine also varies depending on the plane1 of the ultrasound imaging and which part of the thoracic spine is being imaged.1 Ultrasound visibility progressively decreases as one moves up the thoracic spine.1 Currently data are limited on the use of ultrasound to guide or assist thoracic epidural injections.3,4 This chapter briefly outlines the anatomy, the technique of ultrasound imaging, and sonoanatomy of the thoracic spine relevant for thoracic epidural injection.
