Carrier liquid solutions for the production of gas microbubbles, preparation thereof, and use thereof as contrast medium for ultrasonic diagnostics |
摘要 |
The useful lifetime and the amount of microbubbles of a size less than 50 mu m produced by mechanical agitation of an aqueous liquid employed as an ultrasonic contrast medium are increased by employing a liquid containing dissolved therein a tenside which reduces the surface tension of the liquid and a compound which raises the viscosity of the liquid.
