Comparison of ultrasound cephalometry, radiology, and liquor studies in patients with unknown confinement dates.
The accuracy of predicting fetal maturity by ultrasound cephalometry, radiology, and liquor studies in patients with unknown confinement dates has been compared. The best prediction was given by ultrasound cephalometry. Liquor studies were least helpful.
Amniocentesis↗
Fallacy of the fundal height.
The method of estimating gestational age from the height of the fundus uteri during pregnancy has been investigated. Such wide variations occur in the length of the maternal abdomen and umbilical position and in the level of the uterine fundus at each gestational age that the method is not reliable. Assessment of uterine size by pelvic examination in the first trimester of pregnancy correlates more closely with gestational age than assessments made by abdominal palpation of the uterus at a later time.
