Occasionally a transvaginal ultrasound is also needed.

The thickness of this fluid can be precisely measured and this is called the nuchal translucency (or NT) measurement.

Normally the amount of fluid is small, producing a thin NT measurement.

An increased NT measurement does not always mean the baby has a problem but it does increase the risk.

There are established and strict criteria for the accurate measurement of the nuchal translucency.
