Neurography using the intramuscular injection of ionic iodine contrast media.
Our report presents a new method of neurography. Sciatic nerve and lumbosacral plexuses in frogs have been visualized after the intramuscular injection of water and lipid soluble ionic iodine contrast media (Telebrix 300, Potassium Iodide 30% and Lipiodol Ultra Fluid). The ascendant flow of the iodine ions (anions) has been achieved by establishing the electrical potential difference between the injection site and the proximal part of the sciatic nerve and lumbosacral plexus. The application of DC current ensued immediately after the injection. Several minutes later the proximal segments of tibial and peroneal common nerves, as well as the sciatic nerve in its full length, have been visualized on X-Ray film. Lumbosacral plexuses became radioopaque after 20 plus minutes.
