A diagnostic agent composition is provided which comprises a nanoparticle composition and a pharmaceutically acceptable carrier or excipient. The nanoparticle composition comprises a nanoparticulate metal oxide and a phosphorylated polyol, wherein the phosphorylated polyol comprises at least two phosphate groups and one or more hydrophilic groups selected from the group consisting of polyethylene ether moieties, polypropylene ether moieties, polybutylene ether moieties, and combinations of two or more of the foregoing hydrophilic moieties. The disclosure provides detailed guidance on methods of making and using such diagnostic agent compositions. The diagnostic agent compositions provided by the present invention are useful as contrast agents for medical diagnostic imaging techniques such as magnetic resonance (MR) imaging and X-ray imaging. The diagnostic agent composition may be administered to a subject via a variety of techniques, among them injection, inhalation, and ingestion.
提供了一种诊断试剂组合物,包括纳米颗粒组合物和药用可接受的载体或赋形剂。纳米颗粒组合物包括纳米颗粒金属氧化物和磷酸化多元醇,其中磷酸化多元醇包括至少两个磷酸酯基团和一个或多个亲水基团,所述亲水基团选自聚乙二醚基团、聚丙二醚基团、聚丁二醚基团以及两种或两种以上的前述亲水基团的组合。该披露提供了制备和使用此类诊断试剂组合物的详细指导。本发明提供的诊断试剂组合物可用作医学诊断成像技术的对比剂,如磁共振(MR)成像和X射线成像。诊断试剂组合物可以通过多种技术向受试者施用,其中包括注射、吸入和口服。
