Abstract: Alkylphosphocholine analogs incorporating a chelating moiety that is chelated to gadolinium are disclosed herein. The alkylphophocholine analogs are compounds having the formula: or a salt thereof. R1 includes a chelating agent that is chelated to a gadolinium atom; a is 0 or 1; n is an integer from 12 to 30; m is 0 or 1; Y is —H, —OH, —COOH, —COOX, —OCOX, or —OX, wherein X is an alkyl or an arylalkyl; R2 is —N+H3, —N+H2Z, —N+HZ2, or —N+Z3, wherein each Z is independently an alkyl or an aroalkyl; and b is 1 or 2. The compounds can be used to detect solid tumors or to treat solid tumors. In detection/imaging applications, the gadolinium emits signals that are detectable using magnetic resonance imaging. In therapeutic treatment, the gadolinium emits tumor-targeting charged particles when exposed to epithermal neutrons.

Abstract: The present disclosure relates to a magnetic resonance imaging (MRI) contrast agent containing a gadolinium complex, and more specically, to a DO3A-tranexamic acid compound having a structure of a chemical formula 1, or an ester compound thereof, and gadolinium complexes thereof. The DO3A-tranexamic acid compound or the ester compound thereof may be used to prepare gadolinium complexes. The gadolinium complexes exhibit thermodynamic and kinetic stabilities, and show the relaxation rate equal to that of the clinical contrast agent which is currently commercially available. Therefore, the gadolinium complexes can be widely used as an MRI contrast agent.

Abstract: An imaging nanoparticle comprising a plant virus particle having an interior surface and an exterior surface, an imaging agent that is linked to the interior and/or exterior surface, and a layer of biocompatible mineral such as silica coated over the exterior surface, is described. The imaging nanoparticle can be used in method of generating an image of a tissue region of a subject, by administering to the subject a diagnostically effective amount of an imaging nanoparticle and generating an image of the tissue region of the subject to which the imaging nanoparticle has been distributed.

Abstract: What is described is a process for producing high-purity gadobutrol in a purity (according to HPLC) of more than 99.7 or 99.8 or 99.9% and the use for preparing a pharmaceutical formulation for parenteral administration. The process is carried out using specifically controlled crystallization conditions. The more recent developments in the field of the gadolinium-containing MR contrast agents (EP 0448191 B1, CA Patent 1341176, EP 0643705 B1, EP 0986548 B1, EP 0596586 B1) include the MRT contrast agent gadobutrol (Gadovist® 1.0) which has been approved for a relatively long time in Europe and more recently also in the USA under the name Gadavist®.

Abstract: The present invention relates to an imaging diagnostic method, comprising a contrast agent including a contrast enhancer in a magnetic resonance imaging (MRI) assisted diagnosis of carcinoma diseases or carcinomas, in particular of hepatocellular carcinoma (HCC). The contrast agent is preferably a gadolinium compound, preferably Gd-DTPA including iRGD as a contrast enhancer, for the improved imaging of carcinomas, in particular HCC, in MRI. The invention furthermore relates to a method for the risk stratification of patients and subjects using the aforementioned diagnosis.
