    摘要: The invention relates to a method of electrical impedance imaging of a human or animal subject which method comprises parenterally administering to the subject an EII contrast agent and generating an electrical impedance image of at least part of said subject. The contrast agent may be optionally dissolved or dispersed in a physiologically tolerable liquid carrier medium. The contrast agent is capable on dispersion in water of yielding a fluid having an electrical impedance different to that of water and being a water-insoluble particulate material.

    摘要: The present invention relates to contrast agents comprising microbubble-generating carbohydrate microparticles in admixture with an amphiphilic organic acid containing in excess of 20 carbon atoms. The contrast agents exhibit good stability and/or enhanced contrast effect and may be used in diagnostic applications such as ultrasound and MR imaging.

    摘要: The invention relates to a modification of electron spin resonance enhanced magnetic resonance imaging (ESREMRI) in which two magnetically responsive materials (contrast agents) are introduced into the sample being investigated, one contrast agent serving as an ESREMRI free induction decay signal enhancing agent and the other as enhancement suppressing agent. In this way, image contrast may be enhanced further for regions in which the suppressing agent distributes poorly or not at all or which the suppressing agent reaches at a later time than the enhancing agent.

    摘要: There are provided NMR contrast agents comprising water-soluble paramagnetic metal chelates, preferably of Cr(III), Fe(III) or Gd(III), wherein the chelating entity is an anilide group containing organic moiety, preferably a compound of formula I ##STR1## wherein R.sup.1 to R.sup.5 may represent hydrogen or halogen atoms, optionally halogenated alkyl or alkoxy groups or carboxyl groups. The agents are especially suitable for use in NMR imaging of the hepatobiliary system.

    摘要: The invention relates to pharmaceutically acceptable salts of amphiphilic photosensitizing agents which have a water solubility of at least 0.5 mg/ml and to their use in methods of photochemical internalization. Such salts may be formed from a pharmaceutically acceptable base, for example an organic amine such as an amino alcohol, or from a pharmaceutically acceptable acid, for example a sulphonic acid or a sulphonic acid derivative. Due to their increased water solubility, such salts are particularly suitable for use in the preparation of parenteral pharmaceutical preparations, e.g. for use as solutions for injection or infusion.
