Wann Sonographie peripherer Nerven?

High-resolution ultrasound has gained a growing importance in the diagnostic work-up of peripheral nerve disorders in recent times. By means of ultrasound most peripheral nerves of the upper and lower extremities can reliably be visualized. Ultrasound is considered as a complementary method to nerve conduction studies that provides additional information on morphologic changes of the nerve's structure and of its surrounding tissue. It further enables more precise localization of nerval lesion as well as other information about the underlying etiology. The most important indications for ultrasonography are entrapment syndromes like the carpal or cubital tunnel syndrome, traumatic nerve injuries, benign nerve sheath tumors and inflammatory neuropathies.
