OBJECTIVE An early fetal growth lag may be a marker of future complications. We sought to determine the utility of early biometric variables in predicting adverse pregnancy outcomes. METHODS In this retrospective cohort study, the crown-rump length at 11 to 14 weeks and the head circumference, biparietal diameter, abdominal circumference, femur length, humerus length, transverse cerebellar di...

OBJECTIVE To construct reference ranges of fetal ocular distance (interocular and binocular distance) and to evaluate the relationships between the gestational ages and fetal ocular distance. MATERIAL AND METHOD Six hundred and two normal pregnant women were evaluated from the 15th to 40th week of gestation. Fetal ocular distance (interocular and binocular distances) was added to routine biom...

OBJECTIVE To compare the standard methods for ultrasound measurement of fetal head circumference (HC) and biparietal diameter (BPD) (outer-to-outer (BPDoo) vs outer-to-inner (BPDoi) caliper placement), and compare acquisition of these measurements in transthalamic (TT) vs transventricular (TV) planes. METHODS This study utilized ultrasound images acquired from women participating in the Oxfor...

The small size of the head and abdomen in a growth-retarded fetus may lead to inaccurate estimates of gestational age. Therefore, we conducted a study to assess the diameters of the aortic root and pulmonary artery in such fetuses. During the study period, we measured these great vessel diameters at the level of the semilunar valves on all third-trimester obstetric sonograms in which intrauteri...

A retrospective audit was performed for all obstetric patients who had positive CMV IgM results between January 2012 and December 2014 in the Rotunda Hospital, Ireland. In total, 622 CMV IgM positive tests were performed on samples from 572 patients. Thirty-seven patients had a positive CMV IgM result (5.9%) on the Architect system as part of the initial screening. Three patients were excluded ...

Quantitation of fetal parameters by prenatal sonography enables the assessment of menstrual age and fetal development. Appropriate fetal growth can be surmised on the basis of sequential measurements, as well as the relative variation of parameters such as biparietal diameter (BPD), femur diaphysis length (FDL), abdominal circumference (AC 1, and head circumference (HC). Accurate determination ...
