Laudário Report templates 1st trimester anatomy scan

First-trimester anatomy ultrasound report template (normal)

Between 11 and 14 weeks, the exam combines dating, screening for aneuploidies and preeclampsia and an early anatomical assessment. The template below is for a normal exam, with the markers described one by one.

Normal template

FIRST-TRIMESTER ANATOMY ULTRASOUND

FINDINGS:

Single fetus, with cardiac activity present (rate of [x] bpm) and movements present.

Crown-rump length (CRL): [x] mm.

Nuchal translucency: [x] mm, measured according to Fetal Medicine Foundation criteria.

Nasal bone present.

Ductus venosus with positive a-wave. PI: [x].

No tricuspid regurgitation.

Skull with ossified calvarium and falx cerebri present. Choroid plexuses normal in appearance.

Normal facial profile. Stomach and bladder visible in their usual location.

Abdominal wall intact at the cord insertion. Four limbs with visible segments.

[Anterior/posterior] placenta. Three-vessel umbilical cord.

Uterine arteries with a mean PI of [x] ([x] MoM).

IMPRESSION:

Single pregnancy with a live fetus, [x] weeks and [x] days by CRL.

Sonographic markers of aneuploidy within normal limits.

Early anatomical assessment with no abnormalities detectable at this gestational age.

Combined risk for trisomies 21, 18 and 13 and for preeclampsia as per the attached report.

Example: increased nuchal translucency

FINDINGS:

CRL of 64 mm. Nuchal translucency of 3,8 mm (above the 99th percentile for CRL).

Nasal bone present. Ductus venosus with positive a-wave.

IMPRESSION:

Increased nuchal translucency.

RECOMMENDATIONS:

Counseling on invasive diagnostic testing or cell-free fetal DNA screening, and fetal echocardiography.

Fields in brackets are filled in from the exam. The template is a starting point: the report must reflect what was seen and your practice's guidelines.

Frequently asked questions

What is the normal nuchal translucency value?

NT is interpreted by its percentile for CRL. From 3,5 mm (around the 99th percentile) further investigation is indicated, regardless of the calculated risk.

Does the first-trimester anatomy scan replace the second-trimester one?

No. The early anatomical assessment detects major malformations, but the 20 to 24-week anatomy scan is still necessary.
