FETAL HEAD MEASUREMENTS LATERAL VENTRICLE MEASUREMENT
The diameter of the lateral ventricle can be easily measured with sonography.
— The lateral ventricle is measured in the transaxial plane at the level of the atrium.
— The atrium of the lateral ventricle is the optimal site for measuring the lateral ventricle because this it is the first region where ventricular enlargement occurs.
— The calipers are placed at the level of the glomus of the choroid plexus.
— The normal lateral ventricle does not typically measure over 10 mm at the level of the atrium.
