ABSTRACT In women, high-definition ultrasonography provides high-quality images of normal and diseased tissues throughout pregnancy, however there are no veterinary studies describing the use this technology in pregnant dogs. The objective was to evaluate female dogs daily, using (HD) brachycephalic, documenting daily findings maternal-fetal structures. Twelve healthy brachycephalic females wer...

consensus has formed among sonographers, radiologists, obstetricians, and maternal-fetal medicine subspecialists: screening for fetal heart disease deserves the dubious distinction of being one of the most challenging and least successful aspects of fetal ultrasonography. Because of the challenges inherent with screening the fetus for congenital heart disease (CHD), the rate of prenatal detecti...

INTRODUCTION Unilateral or bilateral dilation of the ureters occurs commonly during pregnancy. Ultrasonography is a suitable diagnostic method for hydronephrosis; however, it cannot differentiate obstructive from nonobstructive hydronephrosis. Our aim was to evaluate measurable changes in hydronephrosis induced by a mother's positional changes using ultrasonography to differentiate hydronephros...

Background: As gestational age grows, the risk of newborn respiratory distress syndrome (RDS) diminishes because lungs are last foetal organs to properly mature. While neonatal RDS does not just occur following preterm births, it is often thought as a disorder premature babies. This study sought determine how prenatal lung capacity and Pulmonary artery resistance index (PARI) affected probabili...

OBJECTIVE This study aimed to survey the current clinical practice of first-trimester ultrasonography among members of the Korean Society of Ultrasound in Obstetrics and Gynecology (KSUOG) and to provide basic data for making practical recommendations about first-trimester ultrasonography scan in Korea. METHODS This survey was conducted using a self-administered anonymous questionnaire. The f...

INTRODUCTION Ultrasonography is used routinely during pregnancy to screen and detect fetal abnormalities. However, there are some conditions like anhydramnios (a prevalent state in renal agenesis) or maternal obesity that may limit the diagnostic accuracy of ultrasonography. Magnetic resonance imaging has proven to be useful when ultrasound alone is insufficient to make a correct diagnosis. C...

The evaluation of the fetal face is an important part of every ultrasound examination since detailed facial examination can provide many information alerting the examiner about possible associated anomalies. Face and the brain have the same embryonic origin. By using 2 and 3D ultrasound techniques, it is possible to obtain clear images of different fetal face defects. Incorporation of the 4D ul...

BACKGROUND Evaluation of the cerebellum and vermis is one of the integral parts of the fetal cranial anomaly screening. OBJECTIVES The aim of this study was to create a nomogram for fetal vermis measurements between 17 and 30 gestational weeks. PATIENTS AND METHODS This prospective study was conducted on 171 volunteer pregnant women between March 2013 and December 2014. Measurements of the ...

OBJECTIVE To assess the role of magnetic resonance imaging (MRI) in the prenatal diagnosis of neural tube defects (NTDs). BACKGROUND NTDs comprise a heterogeneous group of congenital anomalies that derive from the failure of the neural tube to close. Advances in ultrasonography and MRI have considerably improved the diagnosis and treatment of NTDs both before and after birth. Ultrasonography ...
