| Abstract: | Computerised Tomographic scans (CT scans) of the brain of 1000 patients were examined for the various indices viz:- Evans ratio, Frontal-horn index, Bi-caudate index and the Cella-media index used in determining the Ventriculo-hemispheric ratio of the brain and it was observed that Evans ratio was 0.27 ± 0.04 in males and 0.26 ± 0.03 in females; Frontal-horn index was 0.33 ± 0.04 in both males and females; Bi-caudate index was 0.13 ± 0.04 in males and 0.11 ± 0.02 in females; Cella-media index was 0.18 ± 0.04 in males and 0.17 ± 0.03 in females. This study was conducted to determine the Ventriculo-hemispheric ratio of the brain in humans, utilising Evans ratio, Frontal-horn index, Bi-caudate index, and the Cella-media index in its clinical application. |
