Growth of the lateral ventricle in normal second-trimester fetuses: Is a nomogram practical?

The purpose of this study was to determine the growth of lateral ventriclar size of fetuses between 15 and 25 weeks of gestation. A prospective study of normal singleton pregnancies was evaluated consecutively. Measurement of the lateral ventricle was performed by transabdominal sonography as a part of routine obstetric examination in 338 fetuses. The mean size of the lateral ventricular atrial diameter for the 338 fetuses was 6.65 ± 0.95 mm. A weak correlation was found between gestational age and lateral ventricle width (R 2 = 0.03, P 2 = 0.062, P
