Ultrasonic contrast agents for color Doppler imaging
First Claim
Patent Images
1. A method of obtaining an ultrasonic image of a patient comprising administering to the patient microparticles comprising a cavity containing a gas or a volatile fluid, which particles upon exposure to an effective color Doppler sonography modality produce a Doppler signal when the particles are essentially motionless in the patient, and imaging said patient with an effective ultrasonic color Doppler modality in a region where said microparticles are essentially motionless.

- 16. A method of obtaining an ultrasonic image of a patient comprising administering to the patient, microparticles comprising a cavity containing a volatile fluid which particles become sited in tissue or a body cavity of said patient and become essentially motionless therein, irradiating such tissue or cavity with an ultrasound frequency of a strength effective to burst said particles and imaging said patient by recording the ultrasound frequencies scattered as a result of said bursting.
