The invention regards new brominated compounds containing one or two phenyl rings with favorable physico-chemical properties, good tolerance profile, stability and suitable pharmacokinetic profile as contrast media for X-ray mammography, their pharmaceutical formulations and radiological application. The described new bromine contrast media will increase the sensitivity and specificity of X-ray mammography especially in problematic cases. The new contrast media have a higher X-ray absorption than iodine in the energy range used by mammography, a high hydrophilicity, lower toxicity and better tolerance profile than corresponding iodinated compounds.
这项发明涉及新的
溴化合物,其中含有一个或两个苯环,具有良好的物理
化学性质、良好的耐受性、稳定性和适合的药代动力学特性,可作为X射线乳腺摄影的造影剂,以及它们的制剂和放射学应用。所描述的新
溴造影剂将提高X射线乳腺摄影的敏感性和特异性,特别是在问题病例中。这些新的造影剂在乳腺摄影所使用的能量范围内比
碘具有更高的X射线吸收率,具有较高的亲
水性,比相应的
碘化合物具有更低的毒性和更好的耐受性。
