[Experimental radiologic imaging of ulnar and median nerves]

This experimental study presents a new method of neurography of the ulnar and median nerves. Subcutaneous injection of water soluble iodine contrast medium (Urotrast 75%-Krka Yugoslavia) in the vicinity of the nerve immediately followed by 12V D.C. electrostimulation resulted in proximal flow of contrast medium along the epineural space versus all other structures of the nerve trunk. On X-ray films epineural space appeared as two parallel linear shadows delineating a lucent stripe which comprises all other nerve structures. By means of this method nerve X-ray images of very high quality have been accomplished for significantly shorter time than required in other procedures. The method is harmless for the patient and easily applicable.
