Value of superb microvascular imaging ultrasonography in the diagnosis of carpal tunnel syndrome

چکیده
The aim of this study was to compare the value of superb microvascular imaging (SMI) in carpal tunnel syndrome (CTS) with that of color Doppler ultrasonography (CDUS) and power Doppler ultrasonography (PDUS).Fifty patients with symptomatic CTS and 25 healthy volunteers were enrolled. The cross-sectional area (CSA), CDUS score, PDUS score, and SMI score of the median nerve (MN) at the carpal tunnel were recorded. The value of different ultrasonography (US) diagnostic strategies was calculated.The blood flow display ratio in the MN of the healthy volunteers had no statistical difference between CDUS, PDUS, and SMI (20%, 32%, and 48%, respectively, P >.05). The blood flow display ratio for SMI in patients was significantly higher than that of CDUS and PDUS (90%, 52%, and 60%, respectively, P <.005). The accuracy of SMI score ≥2 (79%) was much higher than that of CDUS and PDUS (61% and 63%, respectively, P <.05). Comprehensive consideration of SMI and CSA, CSA≥10.5 mm, and/or SMI score ≥2 has the highest accuracy (83%), significantly higher than that of CSA combination with CDUS or PDUS (68% and 69%, respectively, P <.05).SMI is more sensitive to display the blood flow in the MN with CTS than CDUS and PDUS. It might significantly improve the diagnosis value for CTS.

Dominance in hands and cross-sectional area of median nerve in carpal tunnel syndrome
Introduction: Currently, neuroresearchers report that the median nerve shows severity-correlated intracarpal enlargement in idiopathic carpal tunnel syndrome (CTS) as a most common peripheral neuropathic disorder. The purpose of this paper was to investigate ultrasonography morphological findings in patients with idiopathic CTS and comparing some physical properties such as age, gender, BMI wit...

Introduction: Carpal tunnel syndrome (CTS) is a prevalent disorder in women 30 to 60 years old, which is due to compression of median nerve in hand wrist tunnel. As this syndrome is prevalent, diagnostic power of clinical tests are undefined and electrodiagnostic tests are not accessible widely. This study was conducted to determine the diagnostic power of Phalen's test in comparison with NCV. ...
