the outcome and proper management of fetal hydronephrosis have not been completely defined. the purpose of this study was to determine incidence and outcome of infants with a history of prenatal hydronephrosis diagnosed by ultrasound. in a three-year period from 2000 to 2003 we identified 211 cases (271 renal units) of fetal hydronephrosis in which renal pelvic anteroposterior diameter was more...

neonatal ovarian cysts (noc) are usually self-limiting structures, however, large or complex cysts may lead to severe complications. unfortunately, no standard guidelines have been introduced for the management, treatment and follow-up of these cysts. in this report, we aimed to introduce a very large noc without any pre- and post-natal complications. a 30 year-old mother, gravida 2, para 2, wi...

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 feta...

OBJECTIVES To assess the diagnostic value of prenatal magnetic resonance imaging (MRI) in addition to prenatal ultrasound in a case of fetal varicella syndrome. METHODS Comparison of prenatal ultrasound and MRI features obtained at 26 and 32 weeks, respectively, with neonatal imaging (ultrasound, MRI and CT) and macroscopic and microscopic pathology findings in a fatal case of varicella embry...

Investigations into the safety of ultrasonography in pregnancy have focused on the potential harm of ultrasound itself. However, no data have been published regarding the electromagnetic fields that ultrasound devices might produce. This study is the first to measure extremely low-frequency magnetic field (ELF-MF) exposure of clinicians and pregnant women during prenatal ultrasound examinations...

OBJECTIVE To explore obstetricians' experiences and views of the use of obstetric ultrasound in clinical management of pregnancy. METHODS A qualitative interview study was undertaken in 2015 with obstetricians (N = 20) in Norway as part of the CROss Country Ultrasound Study (CROCUS). RESULTS Three categories developed during analyses. 'Differing opinions about ultrasound and prenatal diagno...

OBJECTIVE Prenatal ultrasound exams have become increasingly frequent. Although no serious adverse effects are known, the public health implications would be enormous should adverse effects on auditory development be shown. This study looks to establish a possible correlation between hearing loss and increased prenatal ultrasound exposure. DESIGN Retrospective cohort analysis. SETTING Terti...

The detection of fetal anomalies was one the earliest uses and remains a pivotal application prenatal ultrasound.
