Abstract
Background: This study documented the normal value of total ventricular
volume in adult Malay Kelantan population, the normal ventricular brain ratio
and the differences in between genders.
Methodology: 58 healthy subjects aged 40years and above were
included whom undergone MRI brain examinations in HUSM. Axial and sagittal
T1-weighted images retrieved from PACS were analysed. The brain and
ventricular outlines were delineated using OSIRIX software. The sum of the
ventricular area multiplied by 0.7 were calculated as the total ventricular volume
in each patient. The ventricular brain ratio obtained by dividing the total
ventricular volume with the brain volume and multiplied by 100. The volumes of
ventricle and brain were analyzed using paired t-test. Independent t-test was
used to analyze ventricular of both male and female. P value of less than 0.05
(p<0.05) was taken as significant. Results were expressed as mean ±standard
deviation (SD).
Result: The mean total ventricular volume was 21.67cm3 (12.82), while
that for male and female was 28.14cm3 (15.61) and 16.02cm3 (5.50)
respectively. Mean total ventricular to brain ratio (in percentage) for all subjects
was 1.71 (0.89). Mean VBR for male subjects was 2.09 (1.11) and 1.37 (0.44)
for female. There was significant difference of the mean total ventricular volume
and VBR between male and female subjects (p value <0.05).
Conclusion: This study has obtained the normal mean value for the total
ventricular volume and ventricular brain ratio in adult Kelantan population, which
are statistically significant difference between difference genders.
