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 present invention relates to a method of preparation of formulations of gadolinium metal complexes of the macrocyclic chelator DOTA, which further comprise a small excess of free DOTA. The method uses controlled conditions such that excess gadolinium is present as a precipitate of gadolinium oxide, with filtration to remove the excess, prior to the addition of a defined excess of DOTA chelator. Also provided is a method of preparation of MRI contrast agents based on Gd-DOTA.

摘要： The present invention relates to a class of compounds and to diagnostic compositions containing such compounds where the compounds are iodine containing compounds. More specifically the iodine containing compounds are chemical compounds containing two linked iodinated phenyl groups of the general formula R—N(CHO)—X—N(R3)—R wherein X denoted an optionally substituted alkylene group, R3 denotes a hydrogen atom or an acyl function and each R denotes a triiodinated phenyl residue further substituted by hydrophilic moieties.The invention also relates to the use of such diagnostic compositions as contrast agents in diagnostic imaging and in particular in X-ray imaging, and to contrast media containing such compounds.
