When introduced in diagnostics, two-dimensional (2D) ultrasound revolutionized many fields of clinical medicine.1,2 Among them, the cardiology gained a huge advantage of 2D ultrasonography for postnatal diagnostics and treatment of congenital cardiac defects. Jan Donald, the father of the modern obstetrical ultrasonography, could not predict how helpful and significant ultrasonography will beco...

The numbers of syphilis cases have been increasing considerably, especially in eastern europe, thereby contributing towards greater chances of cases of congenital syphilis. Some of the complications of congenital syphilis can be detected on two-dimensional ultrasonography (2DUS), and these are generally manifested in the second trimester of pregnancy. The commonest ultrasonographic signs are he...

Although estrogen regulates important aspects of maternal cardiovascular physiology, the role of estrogen on uteroplacental and fetal blood flow is incompletely understood. This study tested the hypothesis that chronically suppressing endogenous estrogen production during the second half of baboon pregnancy alters uterine and fetal blood flow dynamics assessed by ultrasonography. Pregnant baboo...

Ingestion of locoweed (Astragalus spp. and Oxytropis spp.) by pregnant livestock may result in fetal malformations, delayed placentation, reduced placental and uterine vascular development, hydrops amnii, hydrops allantois, abnormal cotyledonary development, interruption of fetal fluid balance, and abortion. Ultrasonography of pregnant sheep fed locoweed demonstrated that abortion was first pre...

introduction: estimation of gestational age is an essential component of prenatal care. gestational age is estimated by last menopausal period, fundal height and ultrasonography. serial measurment of fundal height and comparison with lmp predicts the g.a more accurately. since nowadays, ultrasonography is used more frequently during pregnancy, patients have to bear more expenses. but we can use...

BACKGROUND Hypertensive disorders of pregnancy and intrauterine growth restriction (IUGR) are leading causes of maternal and perinatal morbidity and mortality. Failure to detect intrauterine growth restriction in women at high risk has been highlighted as a significant avoidable cause of serious fetal outcome. In this observational study we compare fetal flow using Doppler ultrasonography with ...

Doppler ultrasound is widely used in obstetrics. However, the biological effects of high energy from ultrasonography have not been clearly revealed. Animal studies shown negative on fetus, but humans are limited. The aim this study to evaluate effect early pregnancy weeks (6-12 week) detect fetal cardiac activity outcomes (number births and abortions, type delivery, cesarean indications, birth ...
