Novel ultrasound contrast agents are provided which are covalently linked to a bioorthogonal reactive group, and optionally further coupled to a corresponding bioorthogonal reactive group coupled with a targeting entity. Methods for targeted ultrasound imaging using such contrast agents are also provided comprising the steps of: 1) injecting the contrast agent into a patient and imaging the patient at a site of interest to detect the contrast agent, wherein the detection of the contrast agent indicates the presence of a target within the patient.
提供了新型超声造影剂,其与
生物正交反应基团共价连接,并可选择性地进一步耦合到与靶向实体耦合的相应
生物正交反应基团上。还提供了使用这种造影剂进行靶向超声成像的方法,包括以下步骤:1)将造影剂注入患者并在感兴趣的部位成像以检测造影剂,其中检测到造影剂表示患者体内存在目标。
