ROLE OF ULTRASONOGRAPHY AND MAGNETIC RESONANCE IN THE EVALUATION OF CARPAL TUNNEL SYNDROME, COMPARATIVE STUDY WITH ELECTROPHYSIOLOGICAL EXAMINATION

Abstract

The current gold standard investigation of carpal tmnel syndrome following clinical examination is the nerve conduction studies. However, high-resolution real-time ultrasound examination is considered an accurate, satisfactory and dynamic diagnostic modality for diagnosis of carpal tunnel syndrome. Through the high-resolution images this modality can clearly show the median nerve, related tendons and the intervening tissues and it can help in assessing the possible ctiology. of nerve compression as (tenosynovitis). MRI; with its excellent contrast resolution, have a complementary role of ultrasound in assessment of equivocal & recurrent postoperative cases. It gives a comprehensive anatomical study of the carpal tunnel and its contents.
