USE OF HOLLOW MICROCAPSULES |
摘要 |
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, characterised 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. |
