MRI is a technique for examining the central nervous system (brain and spine). EMG is a complementary technique used to examine the peripheral nervous system (nerve and muscle).
EMG is used to diagnose neuropathy, myasthenia gravis, myopathy and nerve root compression. By placing fine needles into the muscles of a limb, crucial information can be obtained regarding the muscle itself and the nerves which are embedded in it. New York Core Neuroscience uses Dr. Sie Kim, who is a nationally-recognized expert in EMG and who has over 30 years of experience of EMG at the Rusk Institute.
