Abstract: The invention pertains to an echolucent image enhancing hydrophobic, water-immiscible composition, wherein the composition turns echogenic when foamed with air or gas bubbles formed from mechanically inserting (i) air or gas; or (ii) aqueous solution with air or gas into the hydrophobic, water-immiscible composition. The invention also pertains to a foamed echogenic image enhancing hydrophobic, water-immiscible composition and optionally comprising aqueous solution forming a single-phase, said composition comprising air or gas bubbles retained in the composition, and wherein the volume ratio of aqueous solution:hydrophobic, water-immiscible composition is preferably in the range of between 0:100 (i.e. no aqueous solution) and 75:25, preferably between 0:100 and 60:40.

Abstract: The invention pertains to a foamed aqueous image enhancing composition containing cellulose and/or cellulose derivative(s), said composition having a pH between 5.5 and 7, wherein the viscosity of the composition is less than 1800 mPa·sec, and wherein a gas is maintained in the composition for at least 1 minute after preparation. The combination of low viscosity and foam stability makes the composition particularly suitable in patency tests and fallopian tube sterilization checks.
