An ultrasound scan is a medical imaging diagnostic test used in obstetrics for over 20 years. With technological improvements, increased image quality and Doppler techniques, the capabilities and limitations can now be more clearly defined and cost effectiveness taken into consideration. This article reviews just what information a scan can provide and what it can't. The indications are divided into three main time periods. The 18-20 week scan which provides the most information and in many patients will be the only scan required. Reasons for performing the early pre 12 week and late post 26 week scans are also reviewed. Obstetric scanning has added significantly to the development of fetal medicine. This involves the antenatal detection of a condition, that may require treatment or alter management of the pregnant patient. |
