Brain ventricles are a system of cavities or spaces within the brain that are filled with CerebroSpinal Fluid, a clear and colorless fluid that surrounds the brain and spinal cord. Ventricular enlargement, also known as ventriculomegaly, refers to the abnormal enlargement of the brain ventricles. This condition can occur due to various underlying causes, such as hydrocephalus, brain trauma, infections, tumors, or developmental abnormalities.

Aim 

The study aims to determine the normal brain ventricular size in North East population, develop a standardized template, and explore correlations across various age groups within the North East population of  India.

Materials and Methods: The data for the present study are 250 MRI images which are collected from The Department of Diagnostic and Interventional Radiology at the All India Institute Of Medical Sciences, GUWAHATI. The following indices such as Evans index, Callosal angle and Anteroposterior diameter of the lateral ventricle index were calculated.

Results: The ventricular indices showed statistically accurate and well calculated.

Conclusion: A standardized template of normal brain ventricular size helps doctors compare an individual's ventricular size to the norm, aiding in the diagnosis of conditions like hydrocephalus. It guides treatment planning, enables tracking of progress, and enhances patient understanding and engagement in care decisions
