CONTRAST AGENT, PROCESS FOR ITS PREPARATION AND ITS USE FOR ULTRASONIC IMAGING |
| 摘要 |
A contrast agent for ultrasonic imaging and a process for its preparation is disclosed. The contrast agent is an aqueous protein solution which is characterized in that it comprises microbubbles having a mean particle size of about 2 to 4 microns. The microbubbles are produced by subjecting the solution to light-frequency ultrasonic energy. |
