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.
