What are the indications and procedures for using ultrasound in assessing fetal conditions, particularly in cases like trisomy-21?
Understand the Problem
The text discusses various medical procedures and indications for using ultrasound (US) in different situations, particularly regarding fetal monitoring and assessments related to pregnancy and abnormalities such as trisomy-21. It outlines specific methods and procedures involved in utilizing ultrasound effectively in these scenarios.
Answer
Ultrasound, including nuchal translucency, assesses trisomy 21 in fetuses.
Ultrasound is used to assess fetal conditions through nuchal translucency testing in the first trimester to screen for trisomy 21. Procedures include measuring fluid at the back of the fetus's neck, combined with other diagnostic tests, such as amniocentesis.

More Information
Ultrasound is safe and non-invasive, widely used in pregnancy to detect certain conditions early, allowing for better management options.
Tips
Ensure proper timing of ultrasound for accuracy. Misinterpretation of nuchal translucency measurements can lead to false positives.
