The evolving role of ultrasound in obstetrics/gynecology practice.
The value of ultrasound examinations depends heavily on the preparation of the personnel carrying out the examination and the technical capabilities of the equipment they use. Only well-organized regional or national programs are able to provide high level, cost-effective care based on certification of quality. Such certification must include the training of professionals, the definition of competence levels, accreditation of laboratories and the establishment of professional protocols. Together, these factors can guarantee the standard of care and provide legal protection for practitioners. It is worth carrying out routine screening in each pregnancy because the majority of abnormalities occur in pregnancies with low risk. Abnormalities detected on screening cases and the examination of high risk groups should be referred to higher level centers. Here, appropriate technical background and qualified personnel are present to provide cost-effective care. At the same time, necessary invasive interventions can also be performed. A minimum of three screening tests should be performed during pregnancy. The first should be performed at the fetal age of 10-14 weeks to detect abnormalities and pathological conditions in early pregnancy. The second one has to be performed between the fetal ages of 18 and 22 weeks to assess detailed fetal anatomy and rate of development. The third should be performed between the fetal age of 30 and 34 weeks to assess fetal anatomy, rate of development, placentation and circulation. It is worth considering a fourth screening at approximately 36-38 weeks to assess the intrauterine condition of the fetus and determine the appropriate method of delivery. Finally, besides improving the standard of living, education, and hygienic conditions in developing countries, developed countries also have to help improve the standard of pregnancy care. Within this context, the dissemination of diagnostic ultrasound must be given special emphasis.
