What is the preliminary systems review?
The preliminary systems review is an important and comprehensive ultrasound examination, usually performed between weeks 13-17 of pregnancy. The purpose of the examination is to assess the fetal structure at an early stage, and to systematically examine the developing body organs: including the brain, heart, spine, face, limbs, abdominal wall, kidneys and other systems.
The main advantage of the preliminary screening is the ability to identify some findings at a relatively early stage of pregnancy. In cases where a finding requiring further investigation is discovered, timely referral can be made for genetic counseling, additional tests, targeted screening, or appropriate follow-up.
The examination is non-invasive and does not endanger the mother or the fetus.
It is important to know that even when the screening is normal, it is not possible to completely rule out all malformations, syndromes, or developmental problems. Some findings may develop or be discovered only at later stages of pregnancy, therefore the preliminary screening does not replace the late screening and continued pregnancy monitoring.
At the clinic, the review is performed with a thorough, sensitive and professional approach, using particularly advanced ultrasound equipment that enables high-quality and clear imaging of the fetus even in the early stages of pregnancy.
During the examination, emphasis is placed on clear explanation, complete transparency and answering questions, with understanding that this is a significant and exciting examination for the parents. The examination is suitable for women interested in an early, professional and comprehensive assessment of fetal structure and development.
Frequently Asked Questions
No. The preliminary review does not replace the late systems review (weeks 21-24). It constitutes a complementary examination that allows earlier assessment of fetal structure. It is recommended to perform both reviews to obtain a complete and comprehensive picture of fetal health.
Depends on the week of pregnancy. In weeks 13-15, a vaginal examination is required. After week 16, sometimes an abdominal examination may suffice.
The examination usually lasts between 45-60 minutes, depending on the fetus's cooperation and position. Dr. Harel dedicates the time required for a comprehensive and accurate examination, and explains the findings at the end of the examination.
In case of a finding, Dr. Harel will explain the significance clearly and professionally, and refer to appropriate follow-up tests such as amniocentesis, genetic tests, fetal echocardiography or increased monitoring. Early detection allows more options and more time for making informed decisions.
