Fetal Anatomy Scan structured, systematic, detailed.
A comprehensive mid-pregnancy anatomical assessment structured with reference to the current NHS Fetal Anomaly Screening Programme 20-week scan base menu and fetal cardiac protocol.
Detailed assessment informed by current NHS FASP guidance.
The NHS Fetal Anomaly Screening Programme recommends the 20-week screening scan between 18+0 and 20+6 weeks and specifies a base anatomical menu plus a fetal cardiac protocol. UKSONO’s private scan uses this framework to structure a systematic anatomical assessment while clearly remaining separate from the NHS screening programme.
Premium detailed anatomy assessment with clear pricing.
Tunbridge Wells and Orpington are £200. Canary Wharf is £250 and uses its dedicated London booking route.

What we examine, system by system.
The scan is deliberately structured and systematic. Each anatomical area is assessed in the appropriate ultrasound planes where technically obtainable, with limitations documented rather than overlooked.
Head & brain
Skull shape, intracranial anatomy, ventricles, posterior fossa and key midline structures are assessed in standard planes.
Face & lips
The face is reviewed with particular attention to the lips and facial profile where the fetal position allows.
Spine
The spine is examined in longitudinal and transverse views where possible, including the sacral region.
Heart
Cardiac situs, four chambers, outflow tracts and three-vessel/trachea relationships are assessed using the fetal cardiac protocol.
Chest & diaphragm
Thoracic anatomy, lung appearance and diaphragm integrity are reviewed within the limitations of ultrasound.
Abdomen
Abdominal situs and key abdominal structures are reviewed, including the abdominal wall and stomach region.
Kidneys & urinary tract
Both renal areas and the fetal bladder are assessed where visible.
Skeleton & limbs
Long bones, limb presence and general skeletal development are reviewed, with femur length measured as part of biometry.
Key biometric and anatomical views.
Current NHS FASP guidance specifies core anatomical sections and biometric measurements. This private assessment is structured to reflect that level of systematic review.
HC + lateral ventricle
Head circumference plane together with assessment of the atrium of the lateral ventricle.
Transcerebellar view
Suboccipitobregmatic view used to assess the cerebellum and posterior fossa structures.
Lips + nasal tip
Coronal facial view to assess the lips and nasal region where technically obtainable.
Abdominal circumference
Standard AC measurement contributes to fetal biometry and assessment of size.
Femur length
FL is measured in a standard plane and contributes to fetal size assessment.
Spine including sacrum
Sagittal or coronal views are used to assess the spine and sacral region.
A structured look at the fetal heart.
Congenital heart disease can be difficult to detect, so the cardiac component is deliberately systematic. The goal is to assess the core screening views defined in current FASP guidance where technically possible.
Conditions targeted by the NHS 20-week screening pathway.
The NHS FASP programme screens for 11 specified physical conditions. A private anatomy scan cannot guarantee detection of these or every other fetal condition, but the anatomy assessment is structured with reference to the same core screening framework.
Anencephaly
A severe condition affecting development of the brain and skull.
Spina bifida
A neural tube defect affecting the spine and spinal cord.
Cleft lip
An opening or split affecting the upper lip.
Congenital diaphragmatic hernia
A defect in the diaphragm allowing abdominal organs into the chest.
Gastroschisis
An abdominal wall defect with bowel developing outside the abdomen.
Exomphalos
An abdominal wall defect where abdominal contents herniate through the umbilical region.
Serious cardiac conditions
Major congenital heart disease detectable through the FASP cardiac screening protocol.
Bilateral renal agenesis
Absence of both kidneys.
Severe skeletal dysplasia
Severe disorders affecting development of the bones and skeleton.
Edwards’ syndrome (T18)
A chromosomal condition associated with multiple structural abnormalities.
Patau’s syndrome (T13)
A chromosomal condition associated with multiple structural abnormalities.
Preparation for a detailed anatomy scan.
This is a systematic diagnostic examination, so fetal position and technical visibility can affect how quickly all required structures can be assessed.
Detailed findings, documented with appropriate caution.
Your Sonographer explains the scan findings during the appointment and provides a same-day digital report. Ultrasound is a screening and diagnostic imaging tool with recognised limitations, so the report distinguishes clearly between structures seen, structures not fully visualised and any unexpected finding requiring further review.
If you have heavy bleeding, severe or worsening pain, leaking fluid, contractions when not expected, fainting, fever, feel very unwell or have concerns about fetal movements later in pregnancy, contact your NHS maternity unit or maternity triage promptly.
Detailed answers before you book.
Common questions about timing, FASP guidance, the fetal heart, the 11 screened conditions, incomplete views, fetal sex, reporting and private versus NHS screening.
