This structured dynamic book outlines, step by step, an evidence-based systematic approach to the sonographic evaluation of the pelvis in women with suspected endometriosis. This "how to" guide is intended for those with basic ultrasonography skills who want to further develop their capabilities in performing the relevant sonographic techniques to identify endometriosis. Detailed schematics, and corresponding high-resolution ultrasound images and intuitive videos support readers in expanding their technical skills and bridging the gaps in their knowledge of endometriosis ultrasound. The International Deep Endometriosis Analysis (IDEA) group consensus statement was the culmination of the work of 29 authors from 5 continents. With the publication of How to Perform Ultrasonography in Endometriosis the authors intend to provide the basis for quality improvement and benchmarking of ultrasound in the world of endometriosis.
