Establishment of nomograms and reference ranges for intra‐cranial ventricular dimensions and ventriculo‐hemispheric ratio in newborns by ultrasonography

Abstract

Intra-cranial ventricles increase in size with GA but this increase is limited to only a few mm and is proportional to increment in brain tissue. Nomograms and regression equations of AHW, TOD and widths of third and fourth ventricles can assist in objectively assessing ventricular sizes. The almost uniform VHR can be used to screen ventricle size while suspecting hydrocephalus.
