Value of Ultrasound in the Diagnosis of Neurogenic Thoracic Outlet Syndrome Diagnostic imaging techniques for neurogenic thoracic outlet syndrome (NTOS) are lacking. However, a potential valuable diagnostic imaging technique for NTOS is high resolution ultrasound (HRUS) of the brachial plexus. 1 The aim of this prospective study was to determine the diagnostic value of HRUS in NTOS patients.All patients referred to the Catharina Hospital in Eindhoven, The Netherlands, with suspected NTOS were examined following the diagnostic standards for NTOS as described in the SVS TOS Reporting Standards. 2 Medical history, complaints, physical examination, disability of the arm shoulder and hand (DASH), and Cervical Brachial Symptom Questionnaire (CBSQ) score, colour Doppler of the subclavian artery, and Xray of the superior thoracic
