The use of computed axial tomography (CT) in the investigation of neurologic disorders is attractive for its disponibility in the health services. However, the indications of the exam and the correlation with the clinical features has not been frequently studied. We study correlation between the requests of CT and the findings reported by the radiologist, in 367 exams performed from 07/1995 to 07/ 1996. The mean age was 31.7 +/- 22.9 years. The CT were requested in decrescent order of frequency by the Services of Neurology (36.2%), Emergency room (17.4%), Pediatric Neurology (16.9%) and Internal Medicine (5.9%). The CT was more indicated in cases of seizures (30%), headache (26.2%), motor impairment (20.2%) and reduction of conscience level (16.9%). The main hypothetic diagnosis were "to discard anatomic lesions" (9.0%), not specified stroke (8.2%) and neurocisticercosis (8.2%). The result of the CT was normal in 50.4% of the exams specially those requested in cases of headache (94.4%), seizures (71.4%) and "to discard anatomic lesions"(66.7%). The more frequently CT abnormalities were hydrocephalus (5.4%), ischemic stroke (5.4%) and neoplasm (3.5%) The greatest rates of correlation were among those to discard anatomic lesions (66,7%), hydrocephalus (50%), ischemic stroke (50%) and hematoma (50%). We concluded that CT is more helpful if more clinical data is provided in the request form, so aiding the radiologist in the final report.
