Journal club MCQ April 2020

Learning Objectives:

To recognise fetal anomalies were increased in pregnancies with an increased nuchal translucency and discordant CRL
To know that MC pregnancies had a higher incidence of fetal anomalies than DC pregnancies
To quantify the frequency of defects detected at the 11-13 week ultrasound in twin pregnancies
To identify the type of defects that are routinely detected at the 11-13 week ultrasound and what defects are routinely missed at this ultrasound.

a. A NT > 95% was predictive of fetal anomaly whilst discordant CRL was not.

b. A NT > 95% was not preditive of fetal anomaly whilst a discordant CRL was predictive of fetal anomaly.

c. A NT > 95% or discordant CRL was not predictive of fetal anomaly.

d. A NT > 95% and discordant CRL was increased in pregnancies with a defect.
