Tips!
How to get good results
X
Obtain the fetus’s sagittal view as precisely as possible.
X
A higher contrast between the fetus’s palate and nasal bone will yield better results.
X
Preferably, the lateral orientation of the probe should be parallel to the orientation of the fetus’s
body.
X
For optimal results, make sure that the angle between the probe and the fetus’s nasal bone is as
close to 30 degrees as possible.
