Morphometric MRI Study of the Brain Ventricles in Healthy Turkish Subjects

WOS: 000466984400025The aim of this study was to determine the normal values of brain ventricles and indices in healthy subjects in our population using magnetic resonance imaging (MRI) and to reveal sex and age related differences. The MRI of two hundred-sixty-five healthy individuals aged between eighteen and eighty-seven years were examined and the midsagittal and axial images were used for measurements. The measurements were performed from MRI on a Workstation. The following mean values of brain ventricles and indices were observed; frontal horn width (FHW) (33.14 mm); third (3rd) ventricle width (TVW) (3.37 nun); fourth ventricle anteroposterior width (FVWAP) (9.93 mm); fourth ventricle transverse width (FVWT) (12.40 mm); and the maximum transverse inner diameter of the skull (TIDS) (128.75 mm) in females. The same dimensions were 34.85 mm, 3.91 mm, 10.26 mm, 12.81 mm, and 134.68 mm in males, respectively. There were statistically significantly differences in the frontal horn width, third (3rd) ventricle width, and the maximum transverse inner diameter of the skull values in between sexes. The mean values of Evan's index which obtanied with maximum width between the frontal horns of the lateral ventricles divided by the maximum transverse inner diameter of the skull were found as 0.280 +/- 0.172 in females; whereas the same dimensions were calculated 0.276 +/- 0.161 in males. These values were lower in healthy male subjects than females, however; there were no found significantly difference between groups. Present findings obtained from MRI are necessary anatomical baseline data for interpreting pathological changes, planning surgery, and determining presence and progress of some neurological diseases

Corpus Callosum and Ventricle: MRI Determination of Dementia in Turkish Population and Healthy Geriatric Subjects

WOS: 000428048400040The aim of this study was to identify the values of corpus callosum sections and ventricles in Dementia and healthy geriatric subjects using magnetic resonance imaging (MRI) and to establish both gender differences and differences between groups. The MRI results of 163 geriatric subjects (81 healthy individuals; 82 Dementia subjects) aged 60-89 years were studied. The midsagittal and axial images were used for measurements of the corpus callosum and lateral ventricle, respectively on MRI. The mean values of the widths of genu, body, splenium, height of the corpus callosum, longitudinal dimension of the corpus callosum and brain were 8.74 +/- 1.53 mm, 5.37 +/- 0.75 mm, 9.37 +/- 1.33 mm, 25.42 +/- 2.89 mm, 70.99 +/- 3.86 mm, 148.87 +/- 6.67 mm and 8.51 +/- 1.93 mm, 5.37 +/- 0.84 mm, 9.74 +/- 1.17 mm and 25.67 +/- 2.88 mm, 72.41 +/- 4.99 mm, 153.66 +/- 8.00 mm in females and males of healthy geriatric age, respectively. The same measurements were found to be 6.90 +/- 1.66 mm, 4.33 +/- 0.76 mm, 7.94 +/- 1.38 mm, 24.42 +/- 3.11 mm, 69.01 +/- 4.52 mm, 149.18 +/- 7.13 mm and 7.55 +/- 1.98 mm, 4.56 +/- 1.02 mm, 8.60 +/- 1.58 mm, 23.96 +/- 3.51 mm, 73.42 +/- 3.81 mm, 155.38 +/- 8.39 mm in females and males with Dementia, respectively. Additionally, the means of the frontal horn width and Evans index measurements were lower in healthy geriatric subjects, whereas the transverse inner diameter of the skull were higher in healthy geriatric subjects than dementia subjects in both sexes. The observations presented in this report have defined anatomic parameters of healthy and dementia geriatric subjects that need to be taken into consideration for reference data to determine sex discrepancies, and be helpful for radiologists and clinicians
