Application of radio-isotope-labeled perylenequinones onpreparing necrotic myocardium imaging agent

The invention relates to the field of medicine, in particular to the application field of perylenequinones, and more particularly relates to application of radio-isotope-labeled perylenequinones on preparing necrotic myocardium imaging agent. The radio-isotope-labeled perylenequinones have a specific binding force on the exposed DNA of the necrotic myocardium cells, and a radiation source is produced by radioisotopes, thus the specific binding force and the radiation source are utilized, the objective that the necrotic myocardium hibernation cells are effectively detected is achieved by means of a detector used in combination. 本发明涉及药物领域，特别是涉及苝醌类化合物的应用领域，更为具体的说是涉及放射性同位素标记的苝醌类化合物在制备用于坏死心肌成像的药物中的应用。利用放射性同位素标记的苝醌类化合物对于心肌坏死细胞暴露的DNA具有特异性结合力，及放射性同位素产生的射线源，通过探测器的结合使用达到有效检测心肌坏死细胞的目的。
