ObjectiveTo examine the distribution of uterine artery pulsatility index (UtA-PI) at 12, 22, 32 and 36weeks’ gestation in singleton pregnancies which develop pre-eclampsia (PE) and examine the performance of this biomarker in screening for PE. MethodsUtA-PI was measured in 92712 singleton preg- nancies at 11–13weeks, in 67605 cases at 19–24weeks, Ultrasound Obstet Gynecol 2016; 47: 573–579 Published online 22 March 2016 in Wiley Online Library (wileyonlinelibrary.com).

Written informed consent was obtained from the women agreeing to participate in a study on adverse The Fetal Medicine Foundation is a Registered Charity that aims to improve the health of pregnant women and their babies through research and training in fetal medicine. Screening for trisomy 21 can be further improved by assessing additional ultrasound markers such as the nose bone or Doppler flow in the ductus venosus and across the tricuspid valve 2-5. In a study of 44 756 euploid pregnancies and 202 pregnancies with trisomy 21, the addition of ductus venosus pulsatility index for veins (DV‐PIV) with the combined test resulted in a detection rate (DR) of 96% and a FPR of … In three of the 37 studies, some of the maternal blood samples for the cfDNA analysis were obtained after the invasive test 54, 63, 71.

OBJECTIVE: To assess the possible role of Doppler ultrasound assessment of ductus venosus blood flow in screening for chromosomal abnormalities at 10-14 weeks of gestation. METHODS: Ductus venosus flow velocity waveforms were obtained immediately before fetal karyotyping in 486 consecutive singleton pregnancies at 10-14 weeks of gestation. Objective.

Ultrasound A recently described second‐trimester ultrasound marker that is likely to have a major impact on screening for trisomy 21 is nasal bone hypoplasia, defined by a nasal bone that is not visible or with a length of less than 2.5 mm 53. In 1046 singleton pregnancies undergoing amniocentesis for fetal karyotyping at 15–22 weeks, the nasal bone The normal ranges for fetal biometry presented in this section were established from cross-sectional data on 1040 singleton pregnancies at 14–40 weeks of gestation Ultrasound scans after FETO demonstrated an increase in the echogenicity of the lungs within 48 h and improvement in the LHR from a median 0.7 (range, 0.4-0.9) before FETO to 1.8 (range, 1.1-2.9) within 2 weeks following surgery. The median gestation at delivery was 34 (range, 27-38) weeks and in 17 (77.3%) patients delivery occurred after 32 Ultrasound assessment of carotid arterial atherosclerotic disease has become the first choice for carotid artery stenosis screening, permitting the evaluation of both the macroscopic appearance of plaques as well as flow characteristics in the ca Fetal ultrasound measurements can include the crown-rump length (CRL), biparietal diameter (BPD), femur length (FL), head circumference (HC), occipitofrontal diameter (OFD), abdominal circumference (AC), and humerus length (HL), as well as calculation of the estimated fetal weight (EFW).

H., Oepkes, D., Raine-Fenning, N., Reed, K., Salomon Ultrasound images of flow, whether color flow or spectral Doppler, are essentially obtained from measurements of movement. In ultrasound scanners, a series of pulses is transmitted to detect movement of blood. Echoes from stationary tissue are the same from pulse to pulse. Since three-dimensional ultrasound (3DUS) has started to enter clinical use decades ago efforts have been made to evaluate its usability and potential for pediatric imaging . In many fields, particularly in obstetric and prostate imaging but also for assessment of the breast and many other organs mostly in adults, 3DUS has become part of the routine with proven benefits for diagnosis and ultrasound guidance for arterial access, which has been shown to increase first-pass success rates, reduce the time to cannulation, and reduce the risk of hematoma development compared with landmark-based techniques.
