Main findings
This international, cross-sectional online survey revealed a significant disparity between the present-day evidence for the utility of imaging for endometriosis and a diverse international population’s comprehension of this utility. The vast majority of respondents believe surgery is a tool that can diagnose endometriosis and that the non-invasive tools (imaging, blood tests) cannot diagnose endometriosis. Ultrasound could diagnose endometriosis in the opinion of 28.8% of the respondents, and MRI 16.6%. Respondents who had a surgical diagnosis of endometriosis were far less likely to select ultrasound as a diagnostic tool in comparison to those who were diagnosed in a non-surgical fashion. Approximately one-third of respondents were not aware of which phenotype of endometriosis could be diagnosed using ultrasound. However, roughly one in three were aware endometriomas were diagnosable using ultrasound, while one in five and one in seven believed ultrasound could diagnose deep endometriosis and superficial endometriosis, respectively. Access to an advanced TVS in their region was not considered possible for the majority of the respondents.
