Novel ultrasound methods comprising administering to a patient a targeted vesicle composition which comprises vesicles comprising a lipid, protein or polymer, encapsulating a gas, in combination with a targeting ligand, and scanning the patient using ultrasound. The scanning may comprise exposing the patient to a first type of ultrasound energy and then interrogating the patient using a second type of ultrasound energy. The targeting ligand preferably targets tissues, cells or receptors, including myocardial cells, endothelial cells, epithelial cells, tumor cells and the glycoprotein GPIIbIIIa receptor. The methods may be used to detect a thrombus, enhancement of an old or echogenic thrombus, low concentrations of vesicles and vesicles targeted to tissues, cells or receptors.
新型超声波方法包括向患者施加含有脂质、蛋白质或聚合物的气囊组成的有针对性的气囊组合物,该气囊包含一种气体,并与一个靶向配体结合,然后使用超声波扫描患者。扫描可能包括将患者暴露于第一种超声波能量,然后使用第二种超声波能量对患者进行询问。靶向配体首选靶向组织、细胞或受体,包括心肌细胞、内皮细胞、上皮细胞、肿瘤细胞和糖蛋白GPIIbIIIa受体。该方法可用于检测血栓、旧血栓或回声增强、低浓度气囊和靶向组织、细胞或受体的气囊。
