Contrast-Tuned Imaging and Second-Generation Contrast Agent SonoVue: A New Ultrasound Approach to Evaluation of Tubal Patency

HyCoSy with SonoVue and CnTi is a low acoustic pressure technique in which bubbles are not immediately destroyed and can be detected for several minutes. This enables the signal sent to the equipment to be filtered from the echoes emanating from other tissues. Therefore, excluding the fundamental image, the bubbles are clearly observed, with no visualization of pelvic tissues and organs. This allows easier evaluation of tubal patency, provides a more accurate assessment of tubal occlusion, and enables better visualization of the tubal course.
