Introduction: Carpal Tunnel Syndrome (CTS) is one of the main causes of disability. The diagnosis of CTS confirm by electrodiagnostic tests. Sonography is an alternative method for diagnosis of CTS that can investigate anatomy and probable pathology. The aim of this study is to investigate the multiple sonographic diagnostic criteria and compare its diagnostic value with electrodiagnosis. Materials and Methods:In this descriptive-cross sectional study, 84 wrists (42 patients with CTS and 42 individuals without any clinical signs in upper limb) were investigated. Symptomatic patients underwent clinical examination, standard electrodiagnostic evaluation of upper limb and sonographic investigation of median nerve in forearm and wrist. The control group underwent sonographic investigation. Results: Cross Sectional Area (CSA) of Median nerve at distal wrist crease, at the level of Hamate hook and Trapezium, the amount of flexor retinaculum bowing, ratio of CSA at the forearm to distal wrist crease and ratio of CSA at the Pisiform level to distal wrist crease had significant difference in the case group compared to the control group (P-value
