    • This invention relates to novel X-ray contrast agents particularly for use in the cerebrospinal cavities, comprising non-ionic alkanols carrying at least one N-bonded secondary or tertiary amide group and having at least two hydroxyl groups and at least one iodine atom in the molecule. Particularly useful compounds include the N-hydroxyalkyl iodoalkane sulphonamides having at least two hydroxyl groups, tri- and tetra-iodobenzene carrying carbamoyl, acylamino and/or acylaminomethyl substituents and having at least two hydroxyl groups in the molecule and at least one N-hydroxyalkyl group. Particularly preferred compounds comprise 2,4,6-triiodobenzamides which may be 3- and/or 5-substituted with a variety of groups. The compounds all show markedly low toxicities and a number show very high levels of water solubility.
