60 The International Society of Ultrasound in Obstetrics and Gynecology (ISUOG) is a scientific 61 organization that encourages sound clinical practice, and teaching and research for 62 diagnostic imaging in women’s healthcare. The ISUOG Clinical Standards Committee (CSC) 63 has a remit to develop Practice Guidelines and Consensus Statements as educational 64 recommendations that provide healthcare practitioners with a consensus-based approach, 65 from experts, for diagnostic imaging. They are intended to reflect what is considered by 66 ISUOG to be the best practice when they are issued. Although ISUOG has made every effort 67 to ensure that guidelines are accurate when issued, neither the Society nor any of its 68 employees or members accept any liability for the consequences of any inaccurate or 69 misleading data, opinions or statements issued by the CSC. They are not intended to 70 establish a legal standard of care because the interpretation of the evidence that underpins 71 the guidelines may be influenced by individual circumstances and available resources. 72
