Isotopes of gadolinium (64Gd) Naturally occurring gadolinium (64 Gd) is composed of 6 stable isotopes, 154 Gd, 155 Gd, 156 Gd, 157 Gd, 158 Gd and 160 Gd, and 1 radioisotope, 152 Gd, with 158 Gd being the most abundant (24.84% natural abundance). The predicted double beta decay of 160 Gd has never been observed; only a lower limit on its half ...
Gadolinium is a chemical element; it has symbol Gd and atomic number 64. Gadolinium is a silvery-white metal when oxidation is removed. It is a malleable and ductile rare-earth element. Gadolinium reacts with atmospheric oxygen or moisture slowly to form a black coating. Gadolinium below its Curie point of 20 °C (68 °F) is ferromagnetic, with ...
Gadolinium (III) containing MRI contrast agents (often termed simply "gado" or "gad") are the most commonly used for enhancement of vessels in MR angiography or for brain tumor enhancement associated with the degradation of the blood–brain barrier (BBB). [3][4] Over 450 million doses have been administered worldwide from 1988 to 2017. [5]
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body.
Radioactive isotopes are used in medicine for both treatment and diagnostic scans. The most common isotope used in diagnostic scans is Technetium-99m, used in approximately 85% of all nuclear medicine diagnostic scans worldwide. It is used for diagnoses involving a large range of body parts and diseases such as cancers and neurological problems ...

Gadoteric acid, sold under the brand name Dotarem among others, is a macrocycle -structured gadolinium-based MRI contrast agent (GBCA). It consists of the organic acid DOTA as a chelating agent, and gadolinium (Gd 3+), and is used in form of the meglumine salt (gadoterate meglumine). [4][5] The paramagnetic property of gadoteric acid reduces ...
A gallium scan is a type of nuclear medicine test that uses either a gallium-67 (67 Ga) or gallium-68 (68 Ga) radiopharmaceutical to obtain images of a specific type of tissue, or disease state of tissue. Gallium salts like gallium citrate and gallium nitrate may be used. The form of salt is not important, since it is the freely dissolved ...
