1 Practice Guidelines for Performance of the Routine Mid-Trimester Fetal Ultrasound Scan ISUOG Prenatal Ultrasound Screening Task Force

The International Society of Ultrasound in Obstetrics and Gynecology (ISUOG) is a scientific organization that encourages sound clinical practices, teaching, and research for diagnostic imaging in women's health care. The ISUOG Clinical Standards Committee (CSC) has a remit to develop Practice Guidelines and Consensus Statement s as educational recommendations that provide health care practitioners with a consensus-based approach for diagnostic imaging. They are intended to reflect what is considered by ISUOG to be currently the best practices at the time they were issued. Although ISUOG has made every effort to ensure that guidelines are accurate when issued, neither the Society nor any of its employees or members accepts any liability for the consequences of any inaccurate or misleading data, opinion, or statements issued by the CSC. They are not intended to establish a legal standard of care because interpretation of the evidence that underpins the guidelines may be influenced by individual circumstances and available resources.
