Comparison of the diagnostic utility of Electromyography, Ultrasonography, Computed Tomography, Magnetic Resonance Imaging in idiopathic Carpal Tunnel Syndrome determined by clinical findings.

EMG or US could be used as the first-step test in most cases. If they are both available, EMG should be the first choice. They may be performed together when diagnosis is challenging. CT may especially be preferred for bone-related pathological conditions, while MRI may be preferred for soft tissue-related pathological conditions. Even though imaging studies have been proven to be powerful diagnostic tools for CTS, no conclusive information currently exists to support replacing EMG with imaging studies.
