CT ASSESSMENT OF JUGULAR FORAMEN DOMINANCE AND ITS ASSOCIATION WITH HAND PREFERENCE

Three hundred and seven normal CT scans of the head were prospectively analysed to assess jugular foramen dominance. After assessment, hand preference was elicited. Of these, 276 were right-handed and 31 were l eft-handed. Of the right-handed patients: 180 had a larger jugular for amen on the right; 63 had a larger jugular foramen on the left; and in 33 no difference could be discerned. Of the left-handed patients: 11 had a larger jugular foramen on the right; 16 had a larger jugular for amen on the left; and in four no difference could be discerned. The re sults suggested a significant association between jugular foramen domi nance and hand preference.
