摘要:
L'invention concerne une composition de diagnostic comprenant un complexe binucléaire entre un ligand polyaminopolycarboxylique, par exemple l'acide diéthylène triamine pentacétique, un métal paramagnétique tel que Gd et un métal endogène tel que Ca, éventuellement en mélange avec le complexe mononucléaire du même métal paramagnétique et du même ligand. Cette composition peut être utilisée comme agant de contraste pour l'imagerie par résonance magnétique.
摘要:
An agent for modifying H2O relaxation times in NMR diagnosis comprises a polysaccharide having chemically linked to it an organic complexant to which is complexed a paramagnetic metal ion. Polysaccharides include cellulose, starch, sepharose and dextran. Organic complexants include EDTA, DTPA and aminoethyl diphosphonate. A preferred metal ion is Gadolinium (III). The agents can be administered orally or parenterally.

L'invention a pour objet de nouveaux ligands cycliques azotés et des complexes métalliques formés par ces ligands, les applications de ces complexes en imagerie par résonance magnétique, en radiologie par rayons X et comme agents de déplacement chimique in vivo.
摘要:
Complexes formed between a) an amino di- or poly-phosphonate in which phosphonate groups comprise separate carbon atoms and b) a paramagnetic metal ion such as Gd 3+ , have calcified tissue seeking properties which make them useful as contrast agents for investigating bone metabolism by NMR scanning. Two preferred poly-phosphonates are ethylenediamine tetramethylphosphonate and meta- xylene-diamine tetramethylphosphonate.
摘要:
The present invention relates to novel macrocyclic ligands substituted with at least one picolinate group, to the compounds of general formula (I), and also to the radioactive complexes thereof and to the uses thereof in medical imaging and/or in therapy, in particular in interventional radiology. The present invention also relates to a novel process for preparing the ligands according to the invention, and also to the preparation intermediates thereof. In which formula (I) Y 1 , Y 2 and Y 3 are independently a -C(O)OH group or a group of formula (II), at least one of the radicals Y 1 , Y 2 and Y 3 being a group of formula (II).
摘要:
The invention relates to a device for proper draining of an infusion bag under pressure, the device comprising a casing accommodating at least a deformable cushion and a variable volume bladder, wherein said casing comprises a first casing portion (14) defining a cavity (15) having a depth, said deformable cushion being arranged on a surface of said cavity (15) over a cushion thickness, said first casing portion (14) comprising an output side (18) configured to accommodate an output tube of the bag, the first casing portion (14) comprises an elevated part (22) protruding from the cavity (15) and extending from the output side (18) towards an opposite side (19) of the cavity, the deformable cushion covering the cavity and the elevated part, said elevated part defining a support area for the bag.
