Sonographic evaluation of polycystic ovaries.

The morphological features of the ovaries in women with polycystic ovary syndrome (PCOS) have been well described by ultrasound imaging technology. These include enlarged ovary size, multiple small follicles of similar size, increased ovarian stromal volume and echogenicity, peripheral distribution of the follicles, and higher stromal blood flow. Ultrasound identification of the presence of polycystic ovarian morphology (PCOM) has been recognized as a component of PCOS diagnosis.

[Accuracy of prenatal diagnosis of congenital heart defects by fetal echocardiography: a 7-year experience in a Chinese tertiary obstetric center].

Objective: To evaluate the prenatal diagnostic accuracy of fetal echocardiography for congenital heart defects.

Methods: Fetal echocardiographic databases from 2001 to 2007 were searched for patients with a prenatal diagnosis of congenital heart defect, medical records were obtained and the prenatal echocardiographic findings were correlated with postnatal echocardiography results or autopsy findings, if the pregnancy was terminated or the fetus died in utero.

Results: Prenatal diagnosis of congenital heart defects was made in 113 pregnancies at a mean gestational age of 26.

[Fetal echocardiography in diagnosing congenital heart disease prenatally: a multicenter clinical study].

Objective: To evaluate the detection and accuracy of fetal echocardiography for congenital heart defects among high-risk populations.

Methods: A prospective observational study of prenatal diagnosis of congenital heart disease was conducted in two tertiary obstetrics and gynecology hospitals between January 2003 and December 2004. Consecutive fetuses at risk of congenital heart disease underwent detailed fetal echocardiography during the study period.
