Quantitative assessment of neuroimages for ventricular size is an effective approach to reveal structural changes in conditions such as Alzheimer’s Disease, schizophrenia, Huntington’s disease, hydrocephalus and many other neurological and psychiatric disorders. Aim: The present study is being done with the aim to establish normal ventricular indices of brain in both sexes and 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 of Radiology, Ramaiah hospitals. The following indices such as Evans index, bifrontal index, bicaudate index, cella media index, third ventricular index , Huckman’s index and ventricular index were calculated. The parameters were tabulated and statistically analyzed. Results: The ventricular indices showed statistically significant difference between males and females in all the indices except for cella media index. There was positive correlation coefficient between age and indices which was statistically significant. Conclusion: The knowledge of normal anatomy of ventricular system of brain helpful for clinicians, neurosurgeons and radiologists in day to day clinical practice.
