Surgical section.Meeting December 18, 1929Prof. Ya.M. Bruskin. Myeliography and its clinical and experimental evaluation. A new method, proposed in 1921. Early clinical diagnosis of diseases of the spinal cord is difficult, and the establishment of the exact localization is even more so. Myelography in some cases is a valuable diagnostic method. Contrast agents are used for this: iodipine (20-40%) or lipiodol. Both drugs are satisfactory in terms of contrast, but can cause irritation and changes in the membranes.
