An echogenic intracardiac focus (EIF) is a sonographic "soft marker" for aneuploidy, most commonly Down syndrome and trisomy 13. We observe this marker in about 5% of second-trimester ultrasound examinations, which means obstetricians must deal with it on a regular basis.1'2 Aside from its rel...
The imaging method of choice is transvaginal ultrasound. The optimal endometrium prior to embryo transfer is the so-called trilaminar, triple line or "coffee bean" endometrium, typical of the advanced follicular phase. It is formed by two outer hyperechogenic lines that represent the junction ...
Ultrasound-guided microbiopsy was performed; b: histological section (×10 magnification) showing an old fibroadenoma with a largely stromal component (asterisk) responsible for the irregular margins seen with ultrasound. The definition of juvenile FA is not the age at which it appears – only 5 ...
called the “combined screen,” involves an ultrasound measurement of the nuchal fold at the back of the fetus’ neck–called nuchal translucency or NT–and a test of the mother’s blood for certain markers. Then, a second trimester screen is performed using the long-time screening...
