Pregnancy ultrasound in South Delhi

The scan schedule, week by week

Each pregnancy scan answers a specific question at a specific gestation, and having it at the wrong week wastes it. This is the standard schedule for an uncomplicated pregnancy.

Why it matters who holds the probe

In most of Delhi, pregnancy scans are done at a separate imaging centre by a sonologist who has never met you, and the report reaches your obstetrician days later. That works adequately when everything is normal. It works badly when it is not.

Here the scan is performed by the doctor managing your pregnancy. She has your history in her head while she is looking at the images, she explains what she is seeing as she sees it, and if the plan needs to change it changes that afternoon rather than the following week.

What a proper anomaly scan takes

A Level 2 anomaly scan done properly takes thirty to forty-five minutes. It works systematically through the brain, face, spine, heart and outflow tracts, diaphragm, abdominal wall, stomach, kidneys, bladder, limbs, hands and feet, and then the placenta, cord and amniotic fluid.

Cervical length is measured in the same appointment. A cervix under 25 mm at 18–24 weeks is the strongest single predictor of preterm birth we have, and it is treatable — but only if somebody measures it. Many anomaly scans do not include it.

Honest about what scans cannot do

A normal anomaly scan is reassuring but is not a guarantee. Overall detection of major structural anomalies is around 70–80%, and it varies sharply by system: above 95% for anencephaly and major spine defects, around 50–60% for congenital heart disease, and lower for some skeletal and gut conditions. Knowing that beforehand makes a normal result easier to interpret honestly.
