Methods of ultrasound imaging using echogenically persistent contrast agents
First Claim
Patent Images
1. A method of performing a multiple dose ultrasound imaging study of a site within a mammalian subject comprising the steps of:
- a) generating an ultrasound image of the site after administering a first dose of a microbubble ultrasound contrast agent by applying ultrasound at a first energy level;
b) eliminating echogenicity from the first dose of the microbubble ultrasound contrast agent by applying ultrasound at a second energy level, wherein the second energy level is greater than the first energy level; and
c) generating an ultrasound image of the site after administration of a second dose of a microbubble ultrasound contrast agent.

Abstract
The present invention relates to a method of imaging using multiple doses of an echogenically persistent contrast agent. In particular, it relates to the use of ultrasound energy to eliminate residual echogenicity attributed to the first dose of contrast agent prior to administering a second dose of contrast agent for the purpose of acquiring more images.
