Health Imaging June 21, 2022
Researchers recently developed and validated a deep learning model that can identify trisomy 21 in the first trimester of a pregnancy based on findings from ultrasound images.
Trisomy 21—a chromosomal anamoly that causes developmental delays and intellectual disabilities—can be detected via ultrasound and cell-free fetal DNA validation. While DNA screening is up to 99% accurate, it comes at the cost of a high price tag and some studies have suggested that other more cost-effective options, such as ultrasound, should be explored.
When using ultrasound, providers measure fetal nuchal translucency (NT) thickness and other measurements as a reliable way to confirm and rule out Trisomy 21. The accuracy of these measurements depends greatly on the sonographer completing the exam though, which is a cause for concern...
