Aim:
This paper was undertaken to determine the values of brain indexes using
computed tomography (CT) in subject having and not having brain atrophy in
seniors aged 60-90 years in our population.
Materials
and Methods: This study was carried out from the 520 senior subjects (196
subjects having brain atrophy; 324 subjects having no brain atrophy) aged 60-90
years. Measurements of the brain indexes were taken from subjects having axial
brain CT image in the Radiology Department. Also, the data were analysed
according to age and gender.
Results:
The means and standard deviations of the measurements were: the maximum
distance between anterior horns , 37.35±3.76 mm; minimum bicaudate nuclei
distance, 20.76±3.78 mm; maximum internal skull diameter, 135.66±6.51 mm;
maximum internal diameter of frontal bone, 103.23±6.23; internal skull diameter
measured along the same line 116.28±6.60 mm; maximum external diameter of the
skull; 144.08±5.93 mm; cella media distance, 35.88±6.93 mm; and the indices
were calculated and found as: Huckmann number 58.11±6.99 mm; Bifrontal index
0.36±0.03; Bicaudate frontal index
0.55±0.07; Bicaudate index 0.18±0.03; Bicaudate temporal index
0.15±0.03; Schiersmann’s index 4.22±1.16 in subjects having brain atrophy,
respectively. The same values were measured as 32.28±3.19 mm; 15.32±3.05 mm;
133.67±6.71 mm; 102.05±6.13 mm; 113.12±6.04 mm; 141.14±6.12 mm; 28.92±5.79 mm;
47.59±5.63 mm; 0.32±0.03; 0.47±0.08; 0.14±0.03; 0.11±0.02; 5.09±1.13 in healthy
elderly subjects, respectively. There were found significant difference in all
measurements (except Schiersmann’s index) (p<0.05).
Conclusion:
The brain indexes dimensions of Turkish population provides important and
useful knowledge in terms of comparison of abnormalities and atrophy by
clinically.
