Objectives: After studying the article, you should be able to:

• Explain the significant correlation between the nuchal translucency (NT) thickness and ductus venosus (DV) flow profile.

• Describe the potential advantages of adding the diagnostic assessment of DV to NT evaluation.

• Discuss the methods, participants, and sonographic assessments of this study.

1. According to Table 1, the mean nuchal translucency (NT) measurement of participants in the experimental group was:

2. B. 1.3 mm

3. C. 3.2 mm

4. D. 4.7 mm

The ductus venosus pulsatility index (DVPI) values did not show a significant association of karyotype results, with a P-value of:

A. 0.004

B. 0.025

C. 0.125

D. 0.178

The most frequent measure of the ductus venosus Doppler parameter is:

A. Ductus venosus pulsatility index (DVPI)

B. Ductus venosus resistance index (DVRI)

C. Time-averaged maximum velocity (TAMAX)

D. Systole/atrial (S/A) ratio

Of the 232 participants in this study, how many of them underwent amniocentesis?

A. 76

B. 56

C. 41

D. 33

How many times was the ductus venosus (DV) waveform evaluated to improve reproducibility of the examination?

A. Two times per patient

B. Three times per patient

C. Four times per patient

D. Five times per patient
