Gadolinium history

The use of gadolinium-based contrast agents as an alternative to iodinated contrast agents has been reported in a patient with a history of allergy to the latter (3). 

Very recently Kwong et al. (2006) in a group of patients with clinical suspicion of CHD but without history of MI demonstrated that the presence of areas of the LV with gadolinium enhancement carries a high cardiac risk. In addition, the presence of gadolinium enhancement areas has prognostic implications beyond the common clinical, angiographic and functional predictors.

These two elements complete the history of the REEs in the 19th century in the case of gadolinium the decisive role was played by G. de Marignac. 

The history of science of the 20th century knows of many great discoveries and one of the greatest is the discovery of uranium fission under the effect of slow neutrons. The nuclei of uranium-235 isotopes are split into two fragments, each of which is an isotope of one of the elements at the centre of the periodic table. Isotopes of thirty odd elements from zinc to gadolinium can be produced in this way. The yield of the isotopes of element 61 has been calculated to be fairly high—approximately 3 per cent of the total amount of the fission products. 

This final product was similar to that which the scientists had assumed to be the isotope of element 96 with a mass number of 242. The newly discovered element was named curium after the Curies. Another factor prompted this name. In the Mendeleev table element 96 was regarded as an analogue of gadolinium belonging to the rare-earth series the history of which had been started by J. Gadolin in their turn, the Curies were the pioneers of the study of radioactivity whose development produced such amazing results.
