Which type of element is gadolinium?

gadolinium (Gd), chemical element, a rare-earth metal of the lanthanide series of the periodic table. Gadolinium is a moderately ductile, moderately hard, silvery white metal that is fairly stable in air, although with time it tarnishes in air, forming a thin film of Gd2O3 on the surface.

What is gadolinium element family?

Gadolinium is a soft, shiny, ductile, silvery metal belonging to the lanthanide group of the periodic chart.

What is gadolinium element used for?

Its compounds are useful in magnetic resonance imaging (MRI), particularly in diagnosing cancerous tumours. Gadolinium is excellent at absorbing neutrons, and so is used in the core of nuclear reactors.

Where is gadolinium on the periodic table?

Gadolinium is a chemical element with the symbol Gd and atomic number 64. Gadolinium is a silvery-white metal when oxidation is removed. It is only slightly malleable and is a ductile rare-earth element. Gadolinium reacts with atmospheric oxygen or moisture slowly to form a black coating.

How is gadolinium made?

Source: Gadolinium is not found free in nature but is found in a number of minerals: mainly monazite and bastnaesite. Commercially, gadolinium is isolated by ion exchange and solvent extraction. The metal can be produced by the reduction of anhydrous gadolinium fluoride with calcium metal.

Is gadolinium paramagnetic or diamagnetic?

Complexes of the element gadolinium (Gd) are the most widely used of all MR contrast agents. Because of its unique electronic structure (described below), Gd is strongly paramagnetic. Paramagnetism is an intrinsic property of certain materials to become temporarily magnetized when placed in an external magnetic field.

Where is gadolinium produced?

Although China is the main producing nation, gadolinium is also found in countries such as the USA, Brazil, India, Australia, Greenland and Tanzania.

Is gadolinium used in CT scans?

Iodine-based and Gadolinium-based. Iodine-based contrast materials injected into a vein (intravenously) are used to enhance x-ray (including fluoroscopic images) and CT images. Gadolinium injected into a vein (intravenously) is used to enhance MR images.

What is the symbol of gadolinium?


Is gadolinium used in T1 or T2?

Contrast agents containing gadolinium shorten the T1 (or longitudinal) and T2 (or transverse) relaxation time of neighbouring water protons (Fig. 1). These effects increase the signal intensity of T1-weighted images, and reduce the signal intensity of T2-weighted images (5,6).
