CT criteria of hemisphere asymmetry fail to predict language laterality

We compared CT measures of the left and right cerebral hemispheres for two groups of right-handed aphasic adults: those who were left-hemisphere language dominant (n = 89) and those who were right-hemisphere language dominant (n = 15). The distribution of linear CT measures of anterior and posterior widths and lengths did not differ significantly in the two groups. These findings fail to support the hypothesis that CT criteria of hemisphere asymmetry predict language laterality.
