Screening Ultrasound – 1st Trimester (11 Weeks – 13 Weeks + 6 Days)

The First Vital Screening Examination of Pregnancy

The first-trimester screening ultrasound is one of the most critical examinations performed during pregnancy, typically performed between 11 and 13 weeks and 6 days. The objective of this study is to evaluate early fetal development, determine gestational age accurately, and assess the risk of specific chromosomal or structural abnormalities.

Early screening provides essential information about the progression of pregnancy and enables timely planning of subsequent prenatal monitoring when necessary.

What Is Evaluated During the Examination?

During the ultrasound scan, the specialist evaluates:

• Nuchal Translucency (NT) thickness
• Presence of the nasal bone
• Fetal heartbeat (fetal heart rate)
• Precise gestational age
• Overall fetal anatomy and development

The collected measurements are cross-referenced with the exact gestational age and other medical parameters to provide a comprehensive risk assessment.

How Is the Examination Conducted?

The examination is performed using an advanced ultrasound system and is completely safe for both the expectant mother and the fetus.

• Duration: 20–30 minutes.
• Preparation: No special preparation is required.

Frequently Asked Questions

• In which week should the first screening be performed? The examination must be performed strictly between 11 weeks and 13 weeks plus 6 days of pregnancy.
• Can this scan definitively confirm all possible abnormalities? No. A screening assessment calculates the statistical probability of certain risks and helps determine whether further diagnostic testing is required.
• Is this procedure safe for the baby? Yes, absolutely. Diagnostic ultrasound is a non-invasive, safe, and universally accepted method for routine pregnancy monitoring.
