Ultrasonic fetal cephalometry: percentiles curve.
Measurements by ultrasound of the biparietal diameter of the fetal head during pregnancy are a reliable guide to fetal growth. As a ready means of comparison with the normal we constructed from 4,170 measurements in 1,394 cases a curve showing the percentiles distribution of biparietal diameters for each week of gestation.
متن کاملComparison between urinary oestrogen assay and serial ultrasonic cephalometry in assessment of fetal growth retardation.
Urinary oestrogen assay and serial ultrasonic cephalometry were performed on 284 patients who were considered on clinical grounds to be at risk of having a growth-retarded fetus. It was found that ultrasonic cephalometry was significantly better than oestrogens in diagnosing the small-for-dates baby, but that there was no significant difference between the two methods in predicting perinatal as...
متن کاملCephalometry.
With the development of x-ray technology and its application to the craniofacial skeleton, numerous landmarks have been described and studied to better diagnose and plan treatment options for anomalies related to facial architecture. The following text serves to highlight the important landmarks and illustrate how they may be used to plan successful orthognathic reconstruction.
متن کاملUltrasonic features of fetal ebstein anomaly
Objectives: We analyzed and summarized the ultrasonic and anatomical features of fetal Ebstein anomaly to improve the ultrasonographic diagnostic rate. Methods: We analyzed the fetal echocardiographs and either the postnatal echocardiographs or anatomical specimens of 13 cases of fetal Ebstein anomaly. The cases were divided into typical and rare types according to the features of the Ebstein a...
متن کاملIn vitro ultrasonic heating of fetal bone.
The temperature increase measured in vitro in human fetal femurs exposed to 1 MHz, continuous wave ultrasound at 37 degrees C is reported. The temperature is measured with a thermocouple probe and is given for several gestational ages. The initial rate of the temperature increase in the specimens is evaluated and compared to known values of absorption in soft tissue. For example, the initial ra...
