A. MRI of the wrist B. Electromyography (EMG) and nerve conduction studies C. Ultrasound of the wrist D. X-ray of the wrist

Correct Answer is B

Explanation

A. MRI of the wrist can help rule out other conditions, but it is not the most specific test for diagnosing carpal tunnel syndrome.
B. Electromyography (EMG) and nerve conduction studies are the gold standard for diagnosing carpal tunnel syndrome. These tests measure the electrical activity of the muscles and the speed of nerve impulses to confirm nerve compression.

C. Ultrasound of the wrist may be helpful in visualizing the median nerve but is not as definitive as EMG and nerve conduction studies.
D. X-ray of the wrist would not be useful in diagnosing carpal tunnel syndrome as it does not show soft tissue or nerve involvement.
