Endometriosis affects approximately 1 in 9 female-born people and has historically only been diagnosed through invasive laparoscopic surgery after a diagnostic delay of approximately 6.5 years. By the time of diagnosis, many people with endometriosis will report undergoing one (or several) ultrasounds which failed to deliver an outcome or detect their disease. In 2022, women deserve better than this with a timelier and less invasive diagnosis. A comprehensive transvaginal ultrasound can detect deep endometriosis (and in some cases superficial endometriosis too) and is highly valuable in diagnosing the condition, assessing fertility, surgical planning and reducing diagnostic delay. This deep dive day is a must attend for anyone performing or reporting gynaecological ultrasound or clinicians caring for people with endometriosis. Everything you need to know about diagnosing endometriosis with ultrasound will be covered including live scan demonstrations.
