It sits at the junction between the neck (cervical spine) and the upper back (thoracic spine). Clinicians use T1 level as a landmark to describe where symptoms arise, where imaging findings are located, or where a procedure is performed. You may see it in MRI\/CT reports, operative notes, injection documentation, and neurological exams."}
