A routine part of your 3fivetwo antenatal care package includes an extensive 3D ultrasound service. This will include an early pregnancy scan, nuchal scan, detailed normality scan and foetal cardiac scan. 4D ultrasound is also included and can be arranged as a standalone examination.
Ultrasound scans are usually performed to:
- Confirm pregnancy
- Accurately determine gestational age
- Determine viability - to confirm presence of heartbeat
- Determine fetal number
- Reassure the mother that her baby appears to have no gross structural or growth abnormalities
- Determine placental morphology and localisation
Preparation: Please attend your appointment with a full bladder to improve image quality.
Early pregnancy scan: performed at 8-16/17 weeks
Determines the presence of a heartbeat, multiple embryos and gestational age. If there is concern over a possible ectopic pregnancy or in the very early stages of pregnancy, a trans-vaginal scan may be carried out from 6 weeks.
Nuchal Translucency scan: performed at 11-13 weeks
Provides more detailed information including measurement of the ‘Nuchal fold/translucency’ which is used as an indicator (alongside a small or absent nasal bone) for the presence of Down's syndrome and other chromosomal abnormalities. All nuchal scan results are correlated with data from Kings College Hospital (London) to provide individual risk. You may then be offered CVS (chorionic villous sample) at 12 weeks, or an amniocentesis at 16 weeks to provide definitive information for the presence of fetal abnormality.
Detailed Normality scan: performed at 18-20 weeks
This scan will provide detailed information of the baby's major organs and any structural abnormalities present. The sex of your baby may also be determined at this point. Your Obstetrician and/or Ultrasonographer will look closely at the baby's face, spine, head, limbs, chest and abdominal structures and heartbeat. The position of the placenta and amount of amniotic fluid present are also noted.
Foetal Cardiac scan: performed at 22-23 weeks
This scan is carried out by a paediatric Cardiologist (Dr F Casey) and is used solely to image the baby's heart to identify the presence of congenital defects or cardiac abnormalities.
4D Ultrasound: performed at 24-32 weeks
This 4D scan has the added dimension of real time imaging enabling you to capture the miracle of your baby’s development including smiling, yawning, arm stretches, kicking and sleeping.
