摘要:
Targetable diagnostic and/or therapeutically active agents, e.g. ultrasound contrast agents, comprising a suspension in an aqueous carrier liquid of a reporter comprising gas-containing or gas-generating material, said agent being capable of forming at least two types of binding pairs with a target.
摘要:
Targetable diagnostic and/or therapeutically active agents, e.g. ultrasound contrast agents, having reporters comprising gas-filled microbubbles stabilised by monolayers of film-forming surfactants, the reporter being coupled or linked to at least one vector.

摘要:
The present invention relates to metabolically labile esters, and to contrast media for X-ray and magnetic resonance imaging comprising these esters. The esters have formula (I): ##STR1## in which R.sup.3 is asteroid residue. The esters contain at least one iodine atom and/or heavy metal atom. The compound are metabolizable to products which are soluble in body fluids and are physiologically acceptable.
摘要:
A method of electrical impedance imaging (EII) of a subject comprising administering an EII sensitive contrast agent and generating an electrical impedance image of at least part of the subject.
摘要:
Agents for use in improving tissue/tissue contrast in electrical impedance tomography are described. In particular triiodophenyl compounds, metal chelates, magnetic particles, conducting particles and microbubbles may be used.
摘要:
The present invention relates to contrast agents comprising water-soluble microbubble-generating carbohydrate microparticles in admixture with at least 10% w/w relative to the overall composition of a non-surface active material which is less water soluble than the carbohydrate. The contrast agents exhibit useful levels of contrast efficiency and/or stability and may be used in diagnostic applications such as ultrasound and MR imaging.
摘要:
The invention provides the use of a physiologically tolerable, particulate, free or matrix-borne, ferrimagnetic or ferromagnetic material for the manufacture of a diagnostic agent for administration into the gastrointestinal tract, the reproductive tract, the urinary tract, a closed body cavity (e.g. into the synovial fluid or the vasculature) or the musculature for magnetometric imaging of the human or non-human animal body.
摘要:
Heterocylic chelating agents and salts thereof of formula I: ##STR1## wherein X represents a bond, O or S, or a group CHR.sup.1 or NR.sup.3 ; R.sup.1 represents H, a group OR.sup.3 or NR.sup.3 R.sup.3, or an alkyl or alkoxyalkyl group optionally substituted by a hydroxyl group or by a group NR.sup.3 R.sup.3 or CON.sup.3 R.sup.3 ;each R.sup.2 represents H, or an alkyl or alkoxy group optionally substituted by a hydroxyl or alkoxy group;each R.sup.3 represents H, an optionally hydroxylated alkyl group or a group CH.sub.2 Y;Y represents a group COZ, CON(OH)R.sup.4, POZ.sub.2 or SO.sub.2 Z;Z represents a group OR.sup.4, NR.sup.4 R.sup.4 or ##STR2## where each R.sup.11 is H, a hydroxyl group or an optionally hydroxylated alkyl group, s is 0, 1 or 2, and W is CHR.sup.11, NR.sup.11 or an oxygen atom; andeach R.sup.4 represents H, or an optionally mono- or poly-hydroxylated alkyl, alkoxyalkyl or polyalkoxyalkyl group;with the provisos that where s is 0 then W is CHR.sup.11 and that where X represents a bond or CHR.sup.1, at least one group R.sup.1 or R.sup.2 represents other than H or an unsubstituted alkyl group. A process for preparing these agents and methods of heavy metal detoxification using these agents are also described.
