Abstract
Objectives: To detect average dimensions and indices of normal
brain cerebral hemispheres and lateral ventricles in relation to age and
gender.
Subjects & Methods: 135 subjects; 70 males (M) and 65 females (F)
were categorized into 4 age groups (G): GM1 & GFI included subjects
<20 years old, 0M2 & 0F2 included subjects aged 20-40 years, GM3 &
OF3 included subjects aged 40-60 years and GM4 & GF4 included subjects
>60 years old. CT imaging was conducted according to Agapejev;
using high resolution scanner for measuring the width of right (RAW
and left anterior horns (LAW of lateral ventricle, the bifi-ontal distance
(f1) and inner skull width (FF) at this level, the bifi-ontal index (if//fl),
the bicaudate distance (cc), and inner skull width (CC) at this level and
the bicaudate index (cc/CC).
Results: Bifrontal distance was significantly wider in 0M4 than 0M3
and in 0M2 and 0M4 than 0F2 and 0F4. The FF distance increased
progressively but non-significantly among groups 01-3 in both sexes,
but non-significantly decreased in 04 compared to 03 in both sexes.
The FF distance was significantly wider in GM1-3 compared to GF1-3.
Bifrontal index showed non-significant difference between all CF
groups. It showed non-significant difference between GM1-3 groups,
but was significantly higher in 0M4 than 0M3. Bicaudate distance of
0M4 was significantly wider than GM3, in 0F3 than 0P2, 0F4 than
GF3 and in GM1 and 0M4 compared to GFI and 0F4, respectively The
CC distance showed non-significant increase in 0M2 than GMI, but |
