The morphometric study of third ventricle and diencephelon by computerised tomography

Aims of this morphometric study was to analyze the size of third ventricle in relation to the dimension of diencephelon in humans. Ventricular size of males and females was compared. Changes in normal ventricular size with the corresponding changes in the dimension of diencephelon during ageing was also studied and statistically analyzed. The CT images of 112 adult individuals (Age Group 21–60) and 88 ageing individuals (Age above 61) was studied in both males and females. This study suggests that there is negative co-relation of age with dimensions of diencephalon and diencephalon volume is reduced with age. Also there is positive co-relation of age with dimensions of third ventricle and the volume of the third ventricle is enlarged with physiologic ageing.
