    摘要: The present invention relates to a method for improving stability of non fluoridated sugar derivatives, and in particular glucose derivatives such as 1,3,4,6-tetra-O-acetyl-2-O-trifluoromethanesulfonyl-β-D-mannopyranose which are used as precursors for production of radiofluoridated sugar derivatives for use in in vivo imaging procedures such as positron emission tomography (PET). The method comprises storing the non fluoridated sugar derivative in an organic solvent. The resultant formulations of the non fluoridated sugar derivative and cassettes for automated synthesis apparatus comprising the same are also claimed.

    摘要: The invention relates to a process for the preparation of a diagnostic X-ray composition. The composition comprises a non-ionic X-ray contrast agent in a pharmaceutically acceptable carrier. More particularly, the invention relates to a process for secondary production of X-ray compositions comprising X-ray contrast agents with a high dissolution temperature. When using the process of the invention, precipitation is avoided and degradation of the contrast agent is reduced. The process of the invention includes heat treatment of iodinated X-ray contrast agents at low pH.
