CT MEASUREMENTS OF TWO CEREBROVENTRICULAR INDICES AND THEIR RELATION WITH AGE
Journal Title: Journal of Evidence Based Medicine and Healthcare - Year 2017, Vol 4, Issue 6
Abstract
BACKGROUND Cerebroventricular Indices are the relative measurements of the size of lateral ventricle to that of brain. A normal study of these indices are necessary in order to understand any changes in size of the ventricles or other associated abnormalities of the brain. The study uses measurements from Computerised Tomography (CT) which is uniformly calibrated, has reproducible data and is less expensive than MRI. MATERIALS AND METHODS CT scans of 186 apparently healthy normal individuals of age group 1 to 85 years were taken and the subjects were categorized into age intervals of 10 years; males and females taken separately. The linear measurements of lateral ventricle and brain were taken directly from the screen. The cerebrovascular indices were calculated. The mean values in each group were compared with age and sex, using appropriate statistical tests. RESULTS Mean value for Bifrontal index was 0.31±0.03 and that of Bicaudate index was 0.12±0.02. Both indices showed a positive correlation with age. The relative size of the lateral ventricle with the brain did not show any gender difference. CONCLUSION The study results coincide with previous similar studies. Both the indices showed positive correlation with age, of which the Bicaudate index was more sensitive.
