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).
Molecular imaging is broadly defined as the visualization of molecular and cellular processes on either a macro- or microscopic level. Because of its high spatial resolution and ability to noninvasively visualize internal organs, magnetic resonance (MR) imaging is widely believed to be an ideal platform for in vivo molecular imaging.

Gadobutrol contrast media is a clear, colorless-to-pale yellow solution of 1 mmol/mL formulation, available in single dose vials (2 mL, 7.5 mL, 10mL, and 15 mL), single dose pre-filled injections (7.5 mL, 10 mL, 15 mL), and pharmacy bulk packages (30 mL and 65 mL) containing multiple vials. [19]
A contrast agent (or contrast medium) is a substance used to increase the contrast of structures or fluids within the body in medical imaging. [1] Contrast agents absorb or alter external electromagnetism or ultrasound , which is different from radiopharmaceuticals , which emit radiation themselves.
Gadopiclenol was approved for medical use in the United States in September 2022 by the Food and Drug Administration. [2] [12]In October 2023, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Elucirem, intended for contrast-enhanced ...
Iodinated contrast contains iodine.It is the main type of radiocontrast used for intravenous administration.Iodine has a particular advantage as a contrast agent for radiography because its innermost electron ("k-shell") binding energy is 33.2 keV, similar to the average energy of x-rays used in diagnostic radiography.
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to form images of the organs in the body.
