title: A comparison between the computed tomogram and the neuropathological findings in cerebrovascular disease.
abstract: The findings on computed tomography (CT) and neuropathological examinations were correlated in 87 autopsied cases of cerebrovascular disease with regard to the seize and location of lesions, experience of reviewers, and improvement in CT quality. Small infarctions less than 5 mm were very difficult to detect accurately on CT. This was largely because of the limitations in the efficiency of the CT scanner. Accurate diagnosis of medium sized infarctions was also often difficult. This was mainly due to the anatomical location of lesions, the confluence of deep and widened sulci, periventricular white matter, and structures in the posterior fossa. Large infections could be visualized easily on CT, except in their early periods or in cases with hemorrhagic infarctions. The improved accuracy of CT diagnosis for small and medium sized infarctions could not be attained by the experience of reviewers, but was only possible by instrumental improvement of CT quality.
