NT/IPS Ultrasound

The Nuchal Translucency (NT) / Integrated Prenatal Screening (IPS) ultrasound is a specialized first-trimester examination performed between 11 weeks + 2 days and 13 weeks + 3 days of pregnancy. This timing is very important, as the measurements required for screening can only be accurately obtained during this specific stage of pregnancy.

This ultrasound is used as part of early prenatal screening to help assess the risk of certain chromosomal conditions, including:

• Down syndrome (Trisomy 21)
• Trisomy 18
• Other potential developmental concerns

During the examination, the sonographer measures the nuchal translucency, which is the small fluid-filled space at the back of the baby’s neck. The ultrasound will also include assessment of:

• Baby’s growth and gestational age
• Fetal heartbeat
• Early anatomy visible at this stage
• Confirmation of pregnancy location and number of fetuses

This scan is combined with a first-trimester blood test, which must be completed after the ultrasound:

• On the same day, or
• Within 24 hours of the ultrasound appointment

The timing between the ultrasound and bloodwork is essential to ensure accurate screening results.

Please understand that during the NT/IPS ultrasound, we may not always be able to show you the fetus or provide viewing opportunities. This can depend on several factors including:

• Baby’s position and movement
• Gestational age
• Technical limitations
• The specific findings or complexity of the examination

For patient comfort and privacy, we allow one guest to join at the end of the examination whenever possible. This allows the sonographer to focus fully on obtaining the precise measurements and diagnostic images required for screening and radiologist review. In some situations, depending on the findings or technical requirements of the exam, guest viewing may not be possible.

During the scan, the ultrasound screen will not be visible while the technologist is performing the examination. This is intentional and allows the sonographer to concentrate on obtaining the highest quality diagnostic images and measurements.

Your sonographer will assess and confirm your baby’s heartbeat as part of the examination. Fetal heart rate is typically evaluated using M-mode (Motion Mode) ultrasound, which measures and records the movement of the baby’s heart over time. This allows the heart rate to be accurately calculated while using standard ultrasound imaging.

By comparison, the familiar “heartbeat sound” heard during some scans is produced using Doppler audio, which uses a different ultrasound technique to detect motion and blood flow and convert it into an audible sound. Because Doppler technology uses higher acoustic energy than M-mode, current ultrasound safety recommendations support using M-mode for routine fetal heart rate assessment, especially during the first trimester.

While the heartbeat is carefully monitored and documented to ensure your baby’s well-being, audio playback of the heartbeat is not provided during the examination.

Our technologists are specially trained in obstetrical imaging and screening protocols. Their role is to acquire the required images and measurements, but they are unable to provide results or discuss findings during the appointment. All images and measurements are reviewed by a radiologist, and screening results are sent to your referring healthcare provider.

Patients can enjoy free access to both their ultrasound images and reports through PocketHealth following their examination. PocketHealth is a secure online portal that allows you to view, download, and share your imaging records anytime, from any device. This provides an easy and convenient way to keep your pregnancy images and reports accessible throughout your care journey. https://www.pocket.health/en-US/EDI/intro

We understand this is an important and emotional milestone for many families, and we appreciate your understanding and cooperation as we prioritize accurate screening, patient care, and the health of both parent and baby.
