Normal OB Growth Ultrasound Report Template (2nd/3rd Trimester)

Normal second or third trimester growth ultrasound report template: BPD, HC, AC, FL biometry, EFW with percentile, placenta, amniotic fluid and presentation.

EXAMINATION: Obstetric ultrasound for fetal growth, [second/third]
trimester.

CLINICAL HISTORY: [indication]. EDD [date] by [dating method].

COMPARISON: [date of prior, or None available].

TECHNIQUE: Real-time grayscale transabdominal imaging of the gravid
uterus.

FINDINGS:
Fetal number and presentation: Single live fetus in [cephalic/breech]
presentation.
Cardiac activity: Present, at [x] beats per minute.
Biometry:
  Biparietal diameter: [x] cm ([x] weeks [x] days)
  Head circumference: [x] cm ([x] weeks [x] days)
  Abdominal circumference: [x] cm ([x] weeks [x] days)
  Femur length: [x] cm ([x] weeks [x] days)
Estimated fetal weight: [x] g, [x]th percentile for [x] weeks [x] days.
Placenta: [Anterior/posterior/fundal], normal in appearance. The
placental edge is clear of the internal cervical os. No previa.
Amniotic fluid: Normal. [AFI [x] cm / deepest vertical pocket [x] cm].
Fetal anatomy survey: Previously documented; no survey performed on
this limited growth examination.
Maternal structures: The visualized uterus and adnexa are unremarkable.

IMPRESSION:
1. Single live intrauterine pregnancy in [cephalic/breech] presentation.
2. Estimated fetal weight [x] g ([x]th percentile), appropriate for
gestational age.
3. Normal amniotic fluid volume. No placenta previa.

Dictation notes

• A biophysical profile line belongs in the report only when its components were actually scored — never leave a templated “BPP 8/8” in a plain growth study.
• Interval growth is the point of the exam: state the percentile against the prior study, not just today's number.
• Never redate the pregnancy on a growth scan — the established EDD stands, and late biometry measures growth against it.

Frequently asked questions

What biometry belongs in an OB growth ultrasound report?

A growth ultrasound report records biparietal diameter, head circumference, abdominal circumference and femur length, each with its gestational age equivalent, plus the estimated fetal weight with its percentile for the established gestational age. Presentation, cardiac activity, placental position relative to the internal cervical os, and amniotic fluid volume (AFI or deepest vertical pocket) complete the examination.

Should a growth ultrasound change the pregnancy due date?

No. The established due date stands — it was set by the earliest reliable dating, typically first trimester crown-rump length — and late biometry measures growth against it. Redating a pregnancy on a growth scan destroys the very comparison the study exists to make: a fetus measuring small for the established dates may be growth restricted, and moving the due date would hide exactly that finding. Interval percentile against the prior study is the point of the exam.

When does a biophysical profile belong in a growth ultrasound report?

Only when its components were actually scored. The biophysical profile grades fetal breathing, movement, tone and amniotic fluid — plus nonstress testing in the full version — and a templated 'BPP 8/8' left in a plain growth study documents an assessment that never happened. A routine growth examination reports biometry, estimated fetal weight percentile, fluid and presentation; the BPP line is added only when the profile was deliberately performed.
