[Direct cervical myelography using iotrolan 300].

A prospective study of direct cervical myelography with Iotrolan 300 showed the following advantages: 1. Clear differentiation of the nerve roots. 2. Increased retention of contrast in the cervical region. 3. Improved contrast compared with conventional contrast media. 4. Optimal contrast temperature was found to be between 20 and 22 degrees C. 5. Reduction in non-specific and central nervous system complications.
