Figure 4 Anteroposterior lateral ventricle index. Axial T2-weighted magnetic resonance imaging illustrating the anteroposterior lateral ventricle index (ALVI). It is calculated by dividing the maximum anteroposterior diameter of the lateral ventricle (yellow arrow) by the maximum anteroposterior intracranial diameter (white arrow) in the same plane. A: Normal ALVI in a 3-year-old child; B: Increased ALVI in a 3-year-old child with asymmetric biventricular hydrocephalus due to perinatal ischemia.
