SUMMARY & IMPRESSION
- Singleton live intrauterine pregnancy at 20 weeks gestation, confirmed and concordant with dates.
- Fetal biometry is appropriate for gestational age. EFW 318 g, tracking on the 50th centile.
- Complete morphology survey has been performed. All assessed fetal structures are within normal limits. No structural anomaly identified.
- Cardiac anatomy: Normal four-chamber view and outflow tracts. No major congenital heart defect identified on this survey.
- Placenta is posterior, upper segment, not low-lying, normal echotexture.
- Amniotic fluid is normal (AFI 13.8 cm).
- Umbilical cord is three-vessel, normally inserted.
- Doppler indices are normal.
- No soft markers for chromosomal aneuploidy detected.
Note: A normal mid-trimester ultrasound does not exclude all fetal abnormalities. Some conditions may not be detectable by ultrasound. Detection rates are also subject to fetal position, maternal body habitus, amniotic fluid volume, and equipment quality. Clinical correlation and continued antenatal care are recommended.
RECOMMENDATIONS
- Routine antenatal care as per obstetric team.
- Routine growth scan at 28-32 weeks as per local protocol.
- If low-lying placenta was noted, repeat placental localisation scan at 32-34 weeks (not applicable here - placenta is not low-lying).
- Patient to report any reduction in fetal movements promptly.
- Results to be discussed with referring clinician in context of full clinical picture and serum screening results.

This report is based on real-time ultrasound imaging. Findings are limited by image quality, fetal position, and inherent technical constraints of ultrasound. This report should be interpreted in conjunction with clinical history and other investigations.
All values are typical for a normally-growing singleton at 20 weeks. Fill in the patient demographics and clinician details before use. Let me know if you need this as a Word document (.docx) or PDF, or if you want to add any specific findings or patient details.
