The Sonographic Detection of Trisomy 13
Course Overview
Learn how to effectively use ultrasound to detect trisomy 13, a rare chromosomal condition with significant fetal anomalies. This course covers key sonographic findings in both the first and second trimesters, including nuchal translucency, facial clefts, holoprosencephaly, and cardiac anomalies. Gain insights into the distinct facial and central nervous system abnormalities commonly associated with trisomy 13, and learn how to identify soft markers like shortened limbs and echogenic bowel. Detailed protocols for anatomic surveys and dynamic scanning techniques will help you improve detection rates and accurately identify trisomy 13 in high-risk pregnancies. Understand how maternal age and gestational age affect trisomy 13 risk and learn the importance of combining ultrasound findings with genetic testing.
Course Objectives
After completing this activity, the participant will:
Describe the transvaginal ultrasound examination to evaluate fetal anatomy.
Identify major defects on the sonogram associated with Trisomy 13.
Improve patient management through early detection.
Target Audience
Physicians, sonographers, and others who perform and/or interpret ultrasound.
