ABSTRACT
Introduction: Ventricular enlargement is a characteristic physical change that is present frequently in a numberof cerebral disorders encountered in neurologic and psychiatric practice. Quantitative assessment of neuroimagesfor ventricular size is an effective approach to reveal structural changes in conditions such as Alzheimer’sDisease, schizophrenia, Huntington’s disease, hydrocephalus and many other neurological and psychiatricdisorders.Aim: The present study is being done with the aim to establish normal ventricular indices of brain in both sexesand to find the correlation between these indices in different age groups in Indian population.Materials and Methods: The data for the present study are 300 CT scan which are collected from department ofRadiology, Ramaiah hospitals. The following indices such as Evans index, bifrontal index, bicaudate index, cellamedia index, third ventricular index , Huckman’s index and ventricular index were calculated. The parameterswere tabulated and statistically analyzed.Results: The ventricular indices showed statistically significant difference between males and females in all theindices except for cella media index. There was positive correlation coefficient between age and indices whichwas statistically significant.Conclusion: The knowledge of normal anatomy of ventricular system of brain helpful for clinicians, neurosurgeonsand radiologists in day to day clinical practice
