The use of the C.A.T. head scanner in clinical psychiatry
JK Roberts and WA Lishman
Three hundred and twenty-three patients were referred by psychiatrists for
scanning with a 160 X 160 matrix CT 1010 Head Scanner at the Maudsley
Hospital during the first year this machine was in use (1977/1978). Two
hundred and one referrals were for clinical and 122 for research reasons,
50% of the former and 57% of the latter showed some abnormality on their
scans. Review of the patients' notes identified data that were
significantly predictive of abnormal scan results; and the referring
psychiatrists were significantly more able to predict the scan results
correctly during the second six months of the study. Diagnosis, management,
and/or prognosis were influenced in 11.7% of those patients scanned for
clinical reasons.
