Objective To determine whether an echogenic intracardiac focus identified in the second-trimester fetus is related to an increased risk of Down syndrome. Methods During a 10-month period, all women with singleton gestations who underwent second-trime

Many studies have shown that a thickened nuchal fold in a second-trimester fetus is a sonographic sign suggestive of a high risk for Down syndrome. These series have included fetuses already at risk for aneuploidy because of advanced maternal age or

A nonbradycardiac fetal heart rate is associated with a low rate of spontaneous abortion (2%-4%). To determine criteria for predicting impending first-trimester loss when a normal fetal heart rate is identified sonographically, the authors studied 16

We report a sonographic sign consisting of increased skin or soft tissue thickening at the back of the fetal neck during the second trimester, which correlates well with the diagnosis of Down syndrome. Eight hundred consecutive sonograms were perform

Normal first trimester fetal heart rates rise from an average of 100 beats per minute (bpm) at 5 to 6 weeks to 140 bpm at 8 to 9 weeks. The heart rates of 65 consecutive first trimester fetuses between 5+ and 8+ weeks were measured to determine wheth

Cysts of the choroid plexus have been identified ultrasonographically in second-trimester fetuses and usually have regressed by 24 weeks' gestation. Choroid plexus cysts have been linked with trisomy 18, and this possible association has prompted a r

To standardize femur measurement for the identification of fetuses at risk for Down syndrome, sonographers of varying professional experience and background measured the femurs of 20 Down syndrome fetuses and 709 normal control fetuses. A regression

Sonographic structural surveys were made at the time that 904 amniocenteses were performed for genetic evaluation in the second trimester. A sonographic sign was identified which places the fetus at high risk for having Down's syndrome.
