18-20 weeks Fetal Anomaly Scan AO39 v7
This guideline’s objective is to make the purpose of the scan more focused by identifying the main structures that need to be assessed. These key structures lend themselves to identifying a number of conditions that should be screened for. These abnormalities and their expected detection rates form the basis of the NHS Fetal Anomaly Screening Programme FASP .
