  The present invention relates to specific complexes comprising heavy metal ions having an atomic number of 23 or higher and 83 or lower (in particular Ag1+, Ba2+,Pb2 +, Gd3+ and Bi3+) and one or more hematein ligand(s). In particular, the invention relates to the use of the complexes as ex vivo contrast agents for a computed tomography scanning of a biological sample. Moreover, the invention relates to specific ex vivo methods for investigating a biological sample by means of computed tomography scanning methods, wherein the method comprises staining the biological sample with a solution comprising one or more of the complex(es); or wherein the method comprises staining the biological sample with a staining solution comprising hematein, and separately contacting the biological sample with one or more staining solution(s) comprising one or more heavy metal ions having an atomic number of 23 or higher and 83 or lower (in particular Ag1+, Ba2+,Pb2 +, Gd3+ and Bi3+).

  本发明涉及包含具有原子序数为23或更高和83或更低的重金属离子（特别是Ag1+、Ba2+、Pb2+、Gd3+和Bi3+）和一个或多个赫马丁配体的特定络合物。具体而言，本发明涉及将这些络合物用作生物样本的体外造影剂，用于计算机断层扫描。此外，本发明涉及通过计算机断层扫描方法研究生物样本的特定体外方法，其中该方法包括用含有一个或多个该络合物的溶液对生物样本进行染色；或者该方法包括用含有赫马丁的染色溶液对生物样本进行染色，并分别将生物样本与含有原子序数为23或更高和83或更低的重金属离子（特别是Ag1+、Ba2+、Pb2+、Gd3+和Bi3+）的一个或多个染色溶液接触。
