Abstract S UMMARY iffusion tensor imaging and Magnetic resonance neurography are recently showing a promising role in the evaluation of peripheral neuropathies such as median nerve in carpal tunnel syndrome for the effective ability of detecting the nerve track as well as its surroundings and other abnormalities with high resolution and sensitivity, especially by using 3T magnetic fields. However, MRI’s high price, less availability, heaviness of the coil and longer duration compared to other diagnostic tools minimalizing its use to be for postoperative follow up after decompression surgeries. Hence Nerve conduction studies with high resolution ultrasound are still considered the first diagnostic tools for carpal tunnel syndrome. Ultrasonography for its minimal examination time, not invasive, more availability and lower price is preferred as the more satisfactory tool for diagnosis and measurement of the cross sectional area of the median nerve and assessment of the carpal tunnel unless it is an operator dependent and has a less effectiveness than the MRI. Therefore, NCS are the gold standard diagnostic procedure for its high availability, low cost and high accuracy for the detection and grading of neuropathy, however, it is invasive and lack any anatomical or tracking the structural causes of entrapment so other alternatives are nowadays being used |
