Abstract
Computerized tomography (CT) scans without enhancement were performed on 32 children attending a learning disabilities clinic. These 32 were selected because they had subtle lateralizing neurological hemisyndromes (16 right, 16 left). Clinical readings of 25 scans by two independent radiologists “blind” to neurological or historical facts yielded only 5 (20%) concordant abnormal readings. Measurements of ventricular size in all 32 scans yielded even fewer (only 1) judged abnormal. Meaningful hemispheric asymmetries were difficult to define in the present study.
