FIELD: medicine.
SUBSTANCE: invention refers to a contrast medium for ultrasonic imaging in the form of a preparative form. The declared medium contains microparticles a solid coating of which is presented in the form of a stabilizing formulation containing fine lecithin and polyethylene glycol of molecular weight 6000, filled with sulphur hexafluoride in the specific proportions. The preparative form may be suspended in a physiologically acceptable liquid suspension medium in a dose of 0.025-2.0 mg of the microparticles per 100 g of animal's body weight.
EFFECT: invention provides the improved ultrasonic images for at least 5 minutes, higher echogenicity of the analysed tissue.
