五价锝标记的二巯基丁二酸(~(99m)TC(V)—DMS)是一种新的肿瘤显象剂,具有血液清除快,显象时间短等特点,但因其亲肿瘤的作用机制不详,亲肿瘤性(以体内的瘤/脏器比值表示)不太高,临床只有应用于头颈部肿瘤及少数软组织肿瘤的报道,限制了它的应用。
The pentavalent europium-labeled dimercaptosuccinic acid (~(99m)TC(V)-DMS) is a novel tumor imaging agent with features such as rapid blood clearance and short imaging time, but due to its pro-tumor The mechanism of action is unknown, and pro-neoplastic (indicated by the ratio of tumor/organ in vivo) is not too high. Clinical reports of head and neck tumors and a small number of soft tissue tumors have limited their application.
