The fetal anatomy scan report provides a detailed assessment of the baby’s development and detects any structural abnormalities during pregnancy.
Understanding the Purpose of the Fetal Anatomy Scan
The fetal anatomy scan is a critical ultrasound examination performed around 18 to 22 weeks of pregnancy. It serves as a comprehensive check-up that goes beyond confirming the baby’s heartbeat or measuring growth. This scan meticulously examines the fetus’s organs, limbs, and overall development to ensure everything is progressing normally.
Doctors use this scan to detect congenital anomalies or structural defects early on. It helps identify conditions such as heart defects, neural tube problems, or abnormalities in the kidneys and limbs. The information gathered allows healthcare providers to plan appropriate care during pregnancy or after birth. It also gives expectant parents valuable peace of mind.
Since this scan captures detailed images of the fetus’s anatomy, it requires skilled sonographers and high-resolution ultrasound machines. The resulting report is a thorough document summarizing all findings, measurements, and observations made during the procedure.
Key Components of the Fetal Anatomy Scan Report
The report generated from a fetal anatomy scan contains multiple sections that describe various aspects of fetal health and development. Each part provides crucial insights into how well the baby is growing and whether there are any concerns.
1. Biometric Measurements
This section lists precise measurements of different fetal body parts. Common parameters include:
- Biparietal Diameter (BPD): The width of the baby’s head from one side to the other.
- Head Circumference (HC): The distance around the baby’s head.
- Abdominal Circumference (AC): Measurement around the abdomen, which helps estimate fetal weight.
- Femur Length (FL): Length of the thigh bone, an important indicator of skeletal growth.
These numbers are compared against established gestational age norms to assess if growth is on track.
2. Organ Evaluation
The sonographer carefully inspects major organs including:
- Brain: Checking for normal structure and ventricles size.
- Heart: Evaluating chambers, valves, and major vessels for proper formation.
- Lungs: Assessing size and symmetry.
- Kidneys: Confirming presence and normal appearance.
- Stomach & Bladder: Ensuring they are visible and functioning properly.
Any irregularities here may indicate developmental issues requiring further testing.
3. Placenta and Amniotic Fluid Assessment
The report notes placenta location (anterior, posterior, previa) and checks for abnormalities like calcifications or detachment signs. Amniotic fluid volume is measured because both too much or too little fluid can signal potential complications.
4. Fetal Position and Movement
Details about how the fetus lies in the womb—head down or breech—and its activity level are also recorded. These observations help in planning delivery approaches later on.
The Technical Details Behind Measurements
The accuracy of a fetal anatomy scan depends heavily on standardized measurement techniques. Sonographers follow strict protocols to ensure consistency across scans worldwide.
For instance, measuring biparietal diameter involves placing calipers at specific points on axial brain views. Similarly, femur length requires identifying clear bone ends without including cartilage. These technical nuances guarantee that values reflect true fetal size rather than artifacts or errors.
Below is a table summarizing typical biometric parameters with average ranges at 20 weeks gestation:
| Parameter | Average Value at 20 Weeks | Significance |
|---|---|---|
| Biparietal Diameter (BPD) | 46-50 mm | Assesses head width; used for dating pregnancy |
| Head Circumference (HC) | 170-190 mm | Measures overall head size; monitors brain growth |
| Abdominal Circumference (AC) | 140-160 mm | Aids in estimating fetal weight; reflects nutritional status |
| Femur Length (FL) | 30-35 mm | Skeletal development indicator; correlates with gestational age |
These values act as benchmarks doctors use to spot deviations suggesting growth restrictions or overgrowth conditions like macrosomia.

Navigating Abnormalities Reported During the Scan
While most scans reveal normal development, some reports highlight anomalies requiring attention. These findings range from minor variations to significant malformations affecting prognosis.
Commonly detected issues include:
- CNS anomalies: Such as ventriculomegaly or spina bifida detected by abnormal brain structure visualization.
- Congenital heart defects: Irregular chamber sizes or valve malformations may appear in detailed cardiac views.
- Skeletal dysplasias: Unusually short femur length or limb deformities raise red flags about bone disorders.
- Cleft lip/palate: Visible facial irregularities can be spotted with high-resolution imaging.
- Poor amniotic fluid volume: Oligohydramnios or polyhydramnios may indicate placental insufficiency or fetal renal issues.
- Echogenic bowel: Increased intestinal brightness sometimes correlates with infections or cystic fibrosis risk.
- Nuchal fold thickening: A marker linked with chromosomal abnormalities like Down syndrome.
- IUGR (Intrauterine Growth Restriction):If biometric measurements fall below expected norms consistently across scans.
- Limb anomalies:Mismatched lengths or missing digits can be identified clearly through detailed limb imaging.
- Cystic lesions:Sac-like structures in organs such as kidneys suggest developmental cystic diseases requiring follow-up diagnostics.
- Twin complications:If multiple pregnancies exist, unequal growth patterns between fetuses can be assessed accurately through serial scans documented in reports.
- Poor placental placement:A low-lying placenta covering cervix (placenta previa) often emerges in reports prompting delivery planning adjustments to reduce bleeding risks during labor.
- Nuchal translucency thickness measurement: An increased measurement here signals potential chromosomal abnormalities but usually assessed earlier than anatomy scans; sometimes noted if repeated ultrasounds are done late.
- “Fetal spine appears intact without evidence of neural tube defect.”
- “Visualization limited due to maternal obesity; recommend repeat scan if concerns persist.”
- “Placenta positioned anteriorly with no signs of abruption.”
- “Fetal movements observed throughout exam indicating good activity level.”
- “No cystic structures identified within kidneys.”
- “Cardiac four-chamber view normal; outflow tracts partially visualized.”
- “Amniotic fluid index within normal limits.”
