摘要:
The present invention relates to devices and method for melting solid polarised sample while retaining a high level of polarisation. In an embodiment of the present invention a sample is polarised in a sample-retaining cup 9 in a strong magnetic field in a polarising means 3a, 3b, 3c in a cryostat 2 and then melted inside the cryostat 2 by melting means such as a laser 8 connected by an optical fibre 4 to the interior of the cryostat.

Administration by injection or infusion to patients of an injectable liquid for diagnostic or therapeutic purposes is provided by a syringe adapter connectable with an automatic syringe pump and a syringe containing contents to be dispensed. The syringe adapter includes an adapter body receivable by the syringe pump, a syringe retainer for retaining the syringe, and a syringe driver for agitating the contents of the syringe. More particularly the invention relates to an adapter connectable with a syringe pump and methods for delivery of an injectable liquid using such adapter. By connecting an adapter according to the invention to a syringe and a syringe pump, rotation of the syringe is achieved and homogeneity of the injectable is preserved. Particularly, the injectable liquid is an ultrasound contrast agent comprising an aqueous dispersion of gas-filled microbubbles or of particulate matter.

An apparatus for welding closed one end of each of a multiplicity of open-ended tubes suitable for use as brachytherapy capsules includes a welding station having a welding position for welding closed one end of a tube, a rotatable platform having an outside edge, a tube holder positioned adjacent the outside edge, the tube holder movable between a loading position and the welding position, and a feed line positioned in overlying registry with the tube holder at the loading position.
摘要:
The invention provides a method of magnetic resonance investigation of a sample, said method comprising: (i) reacting para-hydrogen enriched hydrogen with a hydrogenatable MR imaging agent precursor containing a non-hydrogen non-zero nuclear spin nucleus to produce a hydrogenated MR imaging agent; (ii) administering said hydrogenated MR imaging agent to said sample; (iii) exposing said sample to radiation of a frequency selected to excite nuclear spin transitions of said non-zero nuclear spin nucleus in said hydrogenated MR imaging agent; (v) detecting magnetic resonance signals of said non-zero nuclear spin nucleus from said sample; and (vi) optionally, generating an image or biological functional data or dynamic flow data from said detected signals.

The invention provides a composition of matter of the formula (I): V-L-R where V is an organic group having binding affinity for an angiotensin II receptor site, L is a linker moiety or a bond, and R is a moiety detectable in in vivo imaging of a human or animal body, with the provisos that where V is angiotensin or a peptidic angiotensin derivative or analog then V-L-R is other than a non-metal radionuclide substituted peptide (e.g. 125I substituted angiotensin II) and L-V is other than simply a peptide with a chelating agent amide bonded to a side chain thereof. This composition of matter may be used to image cardiovascular diseases and disorders.
摘要:
The invention provides a method of magnetic resonance imaging of regional blood oxygenation which comprises administering into the vasculature of a vascularized human or non-human animal subject a T2 blood pool contrast agent, detecting a magnetic resonance signal from at least part of the vasculature of said subject into which said contrast agent distributes, and manipulating said signal to generate an indication of the partial pressure of oxygen (pO2) in at least part of said vasculature.
摘要:
The invention provides a composition of matter of the formula (I): V-L-R, where V is a vector moiety having affinity for an angiogenesis-related endothelias cell receptor, L is a linker moiety or a bond and R is a detectable moiety, characterised in that V is a non-peptidic organic group, or V is peptidic and R is a macromolecular or particulate species providing a multiplicity of labels detectable in in vivo imaging.
摘要:
The invention provides contrast agents for optical imaging of lung cancer in patients. The contrast agents may be used in diagnosis of lung cancer, for follow up of progress in disease development, for follow up of treatment of lung cancer and for surgical guidance. Further, the invention provides methods for optical imaging of lung cancer in patients.
摘要:
This application relates to the use of certain amines of formula (I) for combatting and preventing systemic and local complement activation, and in particular to the use of meglumine and derivatives and optionally salts thereof in combatting and preventing said activation. The amines are also of use in combatting activation of the kinin/kallikrein system or blood coagulation system.
摘要:
The invention provides a process by which ultra low salt content triiodinated aromatic compounds may be isolated from a highly acidic hot triiodination raction reaction medium in a straightforward fashion. The process involves increasing the pH to above 5 a value in the range of 3 to 7 with sodium hydroxide, addition of sodium bisulphite and/or sodium dithionite, addition of seed crystals, cooling slowly, and washing the collected precipitate with water.
