“…(1981) found a comparable effect in 4.8% oftheir cases. This contrasts with the findings of Holt et a! (1982) who found that of99 psychiatric patients who were scanned in one year at two general hospitals (1980/1981), the psychiatrist found the scan result significantly helpful in 25% .…”

“…This has subsequently had a major impact on neurology and neurosurgery, being vastly superior to radioisotope brain scanning, and having definite advantages over other neuroradio logical procedures such as pneumoencephalography and cerebral angiography (Knaus & Davis,1978). Its implicationsfor psychiatryhave been lessobvious and few dramatic findings have resulted when scanning is used to investigate psychiatric patients, even in selected populations (Evans, 1982;Holt et a!, 1982;Larson eta!, 1981;Tsai & Tsuang, 1981;Woods, 1976). If a psychiatrist wishes to refer a patient for CAT head scanning, it is usually necessary for the initial referral to be to a neurologist or neurosurgeon.…”

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.

“…(12) found that the diagnosis changed in 17.9% of their patients following CT scanning, and Holt et al. (17) reported that the CT scan was of significant benefit to the treating psychiatrist in 25% of cases. We report that 20% of the chronic schizophrenia group and 7.9% of the first‐episode group had scans that were of clinical importance, affecting prognosis, diagnosis or management.…”

Objective: To investigate whether patients with first‐episode psychosis or chronic schizophrenia have an increased incidence of magnetic resonance imaging (MRI) brain abnormalities compared with control subjects. Method: Totally 340 clinical MRI reports [Controls (n=98), first‐episode psychoses (n=152), chronic schizophrenia (n=90)] were reported by a neuroradiologist blind to diagnosis and subsequently categorized using referral criteria (immediate, urgent, routine or no referral). Results: Thirty percent of all scans were reported by a neuroradiologist as abnormal, but the majority required no referral. Patients with chronic schizophrenia were more likely to have clinically significant abnormal scans than patients with first episode psychosis or control subjects. In four patients the MRI findings led to the discovery of previously unsuspected pathology. Conclusion: Patients with chronic schizophrenia have an increased prevalence of incidental brain abnormalities. A small proportion of patients with chronic schizophrenia and first‐episode psychosis benefitted directly from MRI scanning.

“…This research acted as a catalyst for a large number of studies utilizing cranial CT in psychiatry. As CT scanners became more widely available to clinicians, they began to be used in mainstream clinical psychiatry to exclude organic brain disease (7–9). The practice became firmly established following the publication by Weinberger (10) of proposed indicators for CT in psychosis.…”
