    • PURPOSE: A method is provided to manufacture a microcapsule with an improved performance at a high yield rate by inputting a volatile compound to a spray-dried aqueous solution. CONSTITUTION: A method of obtaining an image of a part of a patient, comprising: (a) providing microcapsules which have been formed by (i) providing a solution of a material in an aqueous solvent containing water and a liquid of greater volatility than water and (ii) spraying the said solution into a gas such that the aqueous solvent evaporates, thereby forming hallow microcapsules suitable for use as an echogenic contrast agent, (b) injecting the microcapsules into a patient, and (c) subjecting the patient to ultrasonic energy to obtain an image based on the ultrasound reflectivity transmissibility or resonance of the microcapsules, characterized in that at least 5 minutes elapse between steps (b) and (c). The patient can be exercised between administration and imaging without having to be reinjected.
    • 目的:通过将挥发性化合物输入到喷雾干燥的水溶液中,以高产率制造具有改进性能的微胶囊的方法。 构成:获得患者的一部分图像的方法,包括:(a)提供通过以下方式形成的微胶囊:(i)提供材料在含有水的溶剂和比水更大的挥发性的液体中的溶液 和(ii)将所述溶液喷射到气体中,使得水性溶剂蒸发,从而形成适合用作回声造影剂的中性微胶囊,(b)将微胶囊注射到患者体内,和(c)使患者超声波 基于微胶囊的超声反射率传递性或共振获得图像的能量,其特征在于步骤(b)和(c)之间经过至少5分钟。 患者可以在行政和成像之间行使,而不必重新注入。
