Overview of the Anomaly Scan (18-24 Weeks)
The Anomaly Scan is a detailed pregnancy ultrasound performed between 18 and 24 weeks of pregnancy to assess fetal anatomy, growth and selected features of the placenta and amniotic environment.
It is sometimes referred to as a mid-pregnancy or anatomy scan.
Ultrasound uses high-frequency sound waves to create images of the baby without using ionising radiation.
During the examination, the sonographer systematically looks at visible fetal structures including the head, brain, face, spine, chest, heart, abdomen, kidneys, bladder and limbs.
The baby's measurements are also recorded and compared with the expected gestational age.
Placental position and amniotic fluid can also be assessed.
It is important to understand that no ultrasound can identify every physical or genetic condition.
Some abnormalities are difficult to see, may develop later in pregnancy or may not produce visible ultrasound changes.
The standard NHS fetal anomaly screening scan is usually offered between approximately 18 and 21 weeks. This private 18–24-week service should complement, rather than automatically replace, routine NHS maternity and screening care unless your maternity team confirms otherwise.
The Anomaly Scan (18-24 Weeks) is available as a home visit only.
What Does the Anomaly Scan (18-24 Weeks) Assess?
The scan provides a structured assessment of fetal anatomy and selected pregnancy features.
Head and brain - Assesses visible cranial and intracranial structures appropriate to gestational age.
Face - Evaluates selected facial structures where position and image quality allow.
Spine - Examines the visible spinal column and surrounding structures.
Heart - Assesses selected cardiac views, position and visible structure.
Chest - Reviews the lungs and thoracic anatomy.
Abdomen - Assesses the stomach, abdominal wall and selected internal structures.
Kidneys and bladder - Checks whether these structures are visible and developing as expected.
Arms and legs - Reviews the visible long bones, hands, feet and limb development.
Fetal measurements - Head, abdominal and long-bone measurements can be used to assess growth.
Placental position - Identifies where the placenta is situated within the uterus.
Amniotic fluid - Provides an assessment of the fluid surrounding the baby.
Fetal movement and heartbeat - Confirms visible activity and cardiac activity at the time of scanning.
Who May Benefit From the Anomaly Scan (18-24 Weeks)?
The scan may be appropriate for pregnant people seeking detailed mid-pregnancy anatomical assessment.
Pregnant people between 18 and 24 weeks - This is the gestational window for this private service.
People wanting additional fetal anatomical assessment - The scan provides detailed structural imaging.
People who have not yet had a mid-pregnancy anatomy scan - Private imaging may provide additional access, although routine maternity screening should still be maintained.
People requiring follow-up of an earlier ultrasound observation - Selected structures can be reassessed where appropriate.
People who want assessment of fetal growth at mid-pregnancy - Standard biometric measurements can provide additional information.
People wanting placental-position assessment - Placental location can be documented during the examination.
Symptoms and Reasons to Consider the Anomaly Scan (18-24 Weeks)
An Anomaly Scan is usually performed as a planned pregnancy assessment rather than because symptoms are present.
Routine mid-pregnancy anatomical assessment - The scan reviews visible fetal development in detail.
Confirmation of fetal growth - Measurements can be compared with gestational age.
Assessment following an earlier scan concern - Selected anatomy can be reviewed more closely.
Placental-position assessment - Ultrasound can identify whether the placenta is anterior, posterior or low within the uterus.
Uncertain previous imaging - Repeat ultrasound can sometimes provide clearer views as pregnancy progresses.
Additional reassurance alongside routine antenatal care - A private scan can provide another opportunity to assess visible development.
Reduced fetal movements, heavy bleeding, severe abdominal pain, leaking fluid or other acute pregnancy concerns require direct contact with your maternity unit or urgent medical assessment.
A private home ultrasound should not delay assessment through your NHS maternity service.
How to Prepare for the Anomaly Scan (18-24 Weeks)
Fetal position can sometimes prevent all required structures from being seen during one examination.
A repeat or specialist scan may be recommended when imaging is incomplete or a finding requires further assessment.
What Happens During the Anomaly Scan (18-24 Weeks)?
The scan is performed at your home using portable diagnostic ultrasound equipment.
Is the Anomaly Scan (18-24 Weeks) Safe?
Pregnancy ultrasound uses high-frequency sound waves rather than X-rays.
It does not use ionising radiation.
Diagnostic ultrasound has been used extensively during pregnancy and is considered safe when performed appropriately by trained professionals for a clinical purpose.
The examination is generally painless, although pressure may occasionally be required to obtain certain views.
How to Book Your Anomaly Scan (18-24 Weeks)
The Anomaly Scan can be booked privately as a home ultrasound appointment in London.

Select the detailed mid-pregnancy ultrasound service.
Book your home visit
Provide the London address and preferred appointment time.
Confirm your gestation
Ensure the pregnancy is between 18 and 24 weeks at the time of scanning.
Prepare your maternity information
Keep previous scans and maternity notes available where possible.

A qualified ultrasound professional performs the examination.
Receive your report
The authorised report is delivered securely following review.
When Will I Receive My Results?
The expected reporting turnaround is approximately 1 day after the scan.
The sonographer may discuss general observations during or after the appointment.
The formal written report provides the authorised findings.
If an unexpected or potentially significant abnormality is identified, further fetal-medicine or maternity assessment may be recommended.
Understanding Your Anomaly Scan (18-24 Weeks) Results
A reassuring scan may show fetal measurements and visible anatomy consistent with the stage of pregnancy.
The report can also document placental location and amniotic fluid.
An incomplete scan does not necessarily indicate a problem.
Sometimes fetal position, maternal anatomy or technical factors prevent a structure from being seen clearly.
A repeat examination may therefore be required.
If a structural abnormality is suspected, specialist fetal-medicine ultrasound, genetic screening or diagnostic testing may be recommended.
An ultrasound finding does not automatically provide a final diagnosis.
What Can the Anomaly Scan (18-24 Weeks) Detect?
Selected structural abnormalities - The scan can identify some developmental differences affecting fetal organs or anatomy.
Growth abnormalities - Measurements can identify a baby measuring unexpectedly small or large for gestational age.
Placental-position abnormalities - A low-lying placenta can be identified.
Selected skeletal abnormalities - Visible abnormalities of the spine or limbs may be detected.
Selected heart abnormalities - Some significant structural cardiac abnormalities can be visible.
Multiple pregnancy features - Twin or multiple pregnancies can be assessed according to the structures visible.
Limitations of the Anomaly Scan (18-24 Weeks)
Not every condition can be detected - Some developmental and genetic conditions produce no visible ultrasound abnormality.
Fetal position can limit views - A repeat examination can occasionally be required.
Some heart abnormalities are subtle - Specialist fetal echocardiography may be necessary.
Ultrasound does not replace genetic testing - Chromosomal conditions cannot be definitively diagnosed from anatomy ultrasound alone.
This private service does not automatically replace NHS screening - Continue routine maternity appointments and NHS screening unless your maternity team advises otherwise.
