Laudário Report templates 8 to 10 weeks

Ultrasound report at 8, 9 and 10 weeks: ready templates

Between 8 and 10 weeks the embryo already has a heartbeat and movements, and the CRL gives the most accurate dating of the whole pregnancy. Below are the singleton template, the dichorionic twin template, since this is the best stage to determine chorionicity, and the example of an embryo without a heartbeat, with the pregnancy failure criterion written in the report.

8 to 10 weeks template: single embryo

TRANSVAGINAL OBSTETRIC ULTRASOUND

TECHNIQUE:

Transvaginal examination.

FINDINGS:

Anteverted, anteflexed uterus with regular contours, containing an intrauterine gestational sac with corporal implantation.

Yolk sac present, with normal appearance.

Single embryo, with a crown-rump length (CRL) of [x] mm.

Embryonic cardiac activity present, with a rate of [x] bpm.

Embryonic movements present.

No signs of subchorionic hematoma.

Ovaries of normal size and appearance. Corpus luteum in the [right/left] ovary.

No free fluid in the pelvis.

IMPRESSION:

Single intrauterine pregnancy with a live embryo.

Gestational age by CRL: [x] weeks and [x] days.

Estimated due date: [dd/mm/yyyy].

8 to 10 weeks template: dichorionic twin pregnancy

FINDINGS:

Uterus containing two intrauterine gestational sacs, separated by a thick membrane with a lambda sign.

Gestational sac [1]: embryo with a CRL of [x] mm and cardiac activity present, heart rate of [x] bpm.

Gestational sac [2]: embryo with a CRL of [x] mm and cardiac activity present, heart rate of [x] bpm.

Yolk sac present in each gestational sac.

Ovaries of normal size and appearance.

No free fluid in the pelvis.

IMPRESSION:

Intrauterine dichorionic diamniotic twin pregnancy with two live embryos.

Gestational age by the CRL of the larger embryo: [x] weeks and [x] days.

Estimated due date: [dd/mm/yyyy].

Example: embryo without a heartbeat

FINDINGS:

Intrauterine gestational sac, mean sac diameter of 28 mm, containing a yolk sac.

Single embryo, CRL of 12 mm, corresponding to 7 weeks and 3 days.

No embryonic cardiac activity is identified.

Embryonic movements absent.

IMPRESSION:

Intrauterine pregnancy with a 12 mm embryo without cardiac activity.

Finding consistent with pregnancy failure, by the criterion of a CRL of 7 mm or more without cardiac activity.

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.

What must not be left out

CRL with the gestational age and the estimated due date: dating at this stage holds for the rest of the pregnancy.
Heart rate and embryonic movements.
Number of embryos and, in twins, chorionicity and amnionicity.
Subchorionic hematoma, when present, with its measurements.
The criterion stated explicitly when there is pregnancy failure (CRL of 7 mm or more without a heartbeat).

Frequently asked questions

What is seen on an 8-week ultrasound?

The embryo with a CRL of about 15 to 22 mm, a heartbeat and the first movements, along with the yolk sac. The cephalic pole and the limb buds are already identifiable.

What heart rate is expected between 8 and 10 weeks?

The heart rate rises quickly in early pregnancy and peaks, at around 170 bpm, at about 9 to 10 weeks. At this stage, values between 140 and 180 bpm are expected.

Is the cystic image in the cephalic pole at 8 weeks normal?

Yes. It is the rhombencephalon, the posterior brain vesicle, which appears as an anechoic image in the back of the cephalic pole between 7 and 10 weeks and should not be described as abnormal.

And the image at the base of the umbilical cord?

It is the physiological midgut herniation, expected between 8 and 12 weeks. It only deserves attention if it persists after 12 weeks or with a CRL above 45 mm.

When should chorionicity be determined in a twin pregnancy?

In the first trimester, preferably before 14 weeks: the lambda sign indicates a dichorionic pregnancy and the T sign a monochorionic one. After that the membrane thins and the assessment becomes less reliable.

At how many weeks is the embryo called a fetus?

From 10 weeks of gestational age, which correspond to 8 weeks after fertilization.
