Normal anatomy scan

 

Clinical

 

Routine anatomy scan

 

EDD by earliest ultrasound at [ ] weeks: [ ]


Gestational age: [ ] weeks [ ] days ± [7] days.

 

Findings

 

Anatomy scan:


Fetal measurements:


Biparietal diameter (BPD) [ ] mm


Head circumference (HC) [ ] mm


Abdominal circumference (AC) [ ] mm


Femur length (FL) [ ] mm


Nuchal fold [ ] mm.

 

Cardiac activity present


Normal fetal movements


Amniotic fluid: normal


Cord: 3 vessels


Placenta: [anterior/posterior/fundal], [not low lying].

 

Fetal anatomy:


The following were visualised and appear normal:

 

Head, brain, face, spine, heart (4Ch view and great vessels), diaphragm, stomach, abdominal wall, kidneys and bladder, limbs.

 

No maternal adnexal abnormality.

 

Comment

 

Normal anatomy scan.

 

Report conclusions

 

Incomplete anatomy scan

 

Incomplete anatomy scan.

 

Visualisation of the fetal [ ] was limited by [fetal position/maternal habitus, etc]. A follow‑up scan has been arranged for [date].

 

Technically difficult but grossly normal scan

 

Technically difficult scan due to [maternal habitus, etc]. Allowing for this, no fetal anomaly has been identified.

 

Low-lying placenta

 

Normal fetal anatomy.

 

The placenta is low lying. The lower placental margin is [ ] mm from the internal cervical os. A follow-up scan is recommended at 32 weeks.

 

Fetal demise

 

Unfortunately, appearances today are those of a fetal demise at [ ] weeks, [ ] days by [measurements]. [Woman’s name] is aware, and the results have been telephoned to [referrer’s name]. (Please document other relevant findings such as fetal anomaly.)

 

Cervical length screening (in a high-risk woman)

 

The cervix measures [ ] mm and appears normal without funnelling.

 

The cervix is short, measuring [ ] mm, without evidence of funnelling. Follow-up scan and specialist opinion is recommended.

 

The cervix is short, measuring [ ] mm, with funnelling. Results have been telephoned to [referrer’s name].

 

The cervix is completely open, with membranes bulging into the lower cervix/vagina. Results have been telephoned to [referrer’s name].

 

Renal dilatation

 

There is [right/left/bilateral] renal pelvic dilatation, [with/without] peripheral calyceal dilatation (Grade A1/A2/A3). A follow-up scan is recommended at 32 weeks.

 

See Appendix 7: Fetal renal tract dilation charts.

 

Monochorionic-diamniotic twin pregnancy

 

Monochorionic-diamniotic twin pregnancy, [ ] weeks, [ ] days by [earliest scan]. Fortnightly scans to screen for twin-twin transfusion syndrome are recommended from 16 weeks.

 

Isolated muscular VSD

 

Isolated muscular VSD, [ ] mm. Specialist review and detailed fetal echocardiogram is recommended.

 

Isolated peri-membranous VSD

 

Isolated peri-membranous VSD, [ ] mm. Specialist review and detailed fetal echocardiogram is recommended.
