The ultrasound imaging of body cavities and surrounding organs is carried out by introducing into the body cavity an aqueous solution of water-soluble hydrocolloid. The hydrocolloid solution is homogeneous, has a viscosity of 200 to 800 cp at 25 DEG C., and is free of gas bubbles and ultrasound-reflecting solid particles. The introduction of the solution into the cavity displaces air therefrom, and while the solution is retained in the cavity an ultrasonic imaging beam is applied to obtain an imaging contrast in which the solution appears sonolucent, that is, essentially black against the more sonoreflective body tissues and organs. |
