How do you measure fetal ventricles?
Usually in sonographic examinations, the fetal ventricle diameter is measured on an axial plane at the level of the thalami as a line perpendicular to the atrium at the level of the posterior margin of the choroid plexus. Measurement of the lateral ventricle diameter by using MR imaging is performed on a coronal plane.Click to…

Also to know is, what is the normal size of brain ventricles in fetus?In the brain of a healthy fetus, the ventricles are about 10 millimeters wide. However, CSF may become trapped in the spaces, causing them to grow progressively larger. Ventriculomegaly is a term that describes the actual image of the enlarged spaces as it appears on a prenatal ultrasound.Similarly, can mild Ventriculomegaly go away? Ventriculomegaly will significantly worsen in approximately 2-5% of cases. In many fetuses, particularly those with borderline ventriculomegaly, the condition will resolve spontaneously resulting in a normal outcome. The major factor that influences prognosis is the presence of associated abnormalities. In this way, how is Ventriculomegaly measured? Antenatal ultrasound The ventricle is measured from inner margin of the medial ventricular wall to inner margin of the lateral wall. Fetal ventriculomegaly is defined as: >10 mm across the atria of the posterior or anterior horn of lateral ventricles at any point in the gestation.Is Mild Ventriculomegaly normal?The lateral ventricles usually measure less than 10 mm (about ½ inch) each. Mild ventriculomegaly means that one or both of the baby’s lateral ventricles are slightly larger than usual. Less often, ventriculomegaly can be due to changes in the normal flow of brain fluid or changes in the development of the brain.
