USG Obstetric NT/NB/Level 1 (12–14 Weeks) Twins is a specialized first-trimester ultrasound examination performed in twin pregnancies between 12 and 14 weeks of gestation. It is primarily used to assess the growth and development of both fetuses and screen for the risk of chromosomal abnormalities, including Down syndrome. The scan includes measurement of Nuchal Translucency (NT), assessment of the Nasal Bone (NB), confirmation of fetal viability, determination of gestational age, and a detailed Level 1 evaluation of early fetal anatomy, supporting comprehensive prenatal care and pregnancy management.

FAQs

Can the examination assess the growth of both babies?

Yes. Measurements of both fetuses can be obtained to assess growth and compare fetal development, helping identify significant differences in size when present.

. Will I need additional tests after this ultrasound?

Depending on the findings and your doctor's assessment, you may be advised to undergo first-trimester biochemical screening, non-invasive prenatal testing (NIPT), genetic counseling, follow-up ultrasound, or other investigations.

Is the scan safe for the mother and babies?

Yes. Ultrasound uses sound waves and does not involve radiation, making it a safe imaging method during pregnancy.

What is included in the Level 1 assessment?

The Level 1 assessment evaluates early fetal anatomy, fetal heartbeat, growth parameters, gestational age, placental location, and overall pregnancy progress.

When should this scan be performed?

The examination is typically performed between 12 and 14 weeks of pregnancy, when NT and NB assessments are most accurate.

What are the advantages of USG Obstetric NT/NB/Level 1 (12–14 Weeks) – Twins?

This examination provides an early assessment of both fetuses, fetal growth, NT, nasal bones, early anatomy, viability, gestational age, and chorionicity/amnionicity. It helps identify pregnancies requiring closer monitoring and supports appropriate prenatal screening and management.
