Bilateral Split Sciatic Nerve<unk>  <unk>  is the direct imaging of nerves in the body by optimizing selectivity for unique MRI water properties of nerves. It is a modification of<unk><unk>  imaging. This technique yields a detailed image of a nerve from the<unk>  signal that arises from in the nerve itself rather than from surrounding tissues or from fat in the nerve lining. Because of the intraneural source of the image signal, the image provides a medically useful set of information about the internal state of the nerve such as the presence of irritation, nerve swelling (edema), compression, pinch or injury. Standard<unk><unk>  images can show the outline of some nerves in portions of their courses but do not show the intrinsic signal from nerve water.<unk>  is used to evaluate major nerve compressions such as those affecting the sciatic nerve (e.g. piriformis syndrome), the brachial plexus nerves (e.g. thoracic outlet syndrome), the pudendal nerve, or virtually any named nerve in the body. A related technique for imaging neural tracts in the brain and spinal cord is called<unk><unk>  tractography or diffusion tensor imaging.
