  1. Normal fetal anatomy

  2. Anatomy Scan • Indications • Identify fetal abnormalities • Identify IUGR • Dating • Placental localisation • Timing • 16-20 weeks • 22-24 weeks • Machine • Good quality machine • TGC sliders • Record images • High quality curvelinear probe • Problems • Incorrect dates • Poor views • Fetal position

  3. Routine • History and consent from patient • Previous child with abnormality • Family history of abnormality • Exposure to teratogens eg drugs, infections • Explain limitations • Growth scan • Placental localisation • Anatomy

  4. Fetal head and face • BPD and HC • Cerebellar view • TCD = gestation • Foramen magna < 10mm • Nuchal fold < 6mm • Lateral ventricles • Posterior aspect ventricle, Perpendicular to falx • <12mm normal, 12-15mm moderate, >15mm severe • Orbits • Inner to inner border, 1/3 ratio of eyes and bridge of nose • Lips and nose • Exclude cleft lip • Profile • Micrognathia, proboscis

  6. Fetal trunk • Coronal section • Heart, stomach, diaphragm and bladder • Sagittal section of anterior abdominal wall • Kidneys • Coronal • Transverse • Diaphragms sagittal view • Umbilical cord insertion • Two umbilical arteries

  7. Fetal trunk • Coronal section • Heart, stomach, diaphragm and bladder • Sagittal section of anterior abdominal wall • Kidneys • Coronal • Transverse • Diaphragms sagittal view • Umbilical cord insertion • Two umbilical arteries

  8. Fetal heart • Reduce gain • Situs • 4 Chamber view • FHR and rhythm • Interventricular septum • LVOT • RVOT • (Aortic arch) • (Ductal arch)

  9. Fetal heart • Situs • 4 Chamber view • FHR and rhythm • Interventricular septum • LVOT • RVOT • (Aortic arch) • (Ductal arch)

  10. Fetal Spine and limbs • Spine- reduce total gain • Sagittal with skinline in view • Coronal • Transverse- 3 ossification centres ‘tight’, not splayed • Follow limb from trunk noting side • Full length all 12 bones • Exclude club foot • Feet- plantar view and count toes • Hands- open if possible and count fingers and thumb
