What this trial studies
This clinical trial investigates the effectiveness of contrast-enhanced ultrasound using SonoVue® in diagnosing adnexal torsion, a gynecological emergency that can lead to severe complications if not treated promptly. The study aims to improve diagnostic accuracy compared to standard pelvic ultrasound and Doppler flow analysis, which have shown variable sensitivity. Participants will undergo the contrast-enhanced ultrasound in addition to standard care, with the goal of providing a more definitive diagnosis before surgical intervention. The trial is designed for women with a strong suspicion of adnexal torsion who are scheduled for surgery.
Why it matters
Potential benefit: If successful, this approach could lead to quicker and more accurate diagnoses of adnexal torsion, potentially improving patient outcomes and preserving fertility.
How similar studies have gone: While there is limited data on the use of contrast-enhanced ultrasound for this specific condition, similar imaging techniques have shown promise in improving diagnostic accuracy in other medical contexts.
