title: Computed tomography and CSF spectrophotometry. Diagnosis and prognosis in 300 patients with cerebrovascular disease.
abstract: Computed tomography (CT) has been reported to show normal findings in 13-52% of patients with cerebrovascular diseases. Among factors deciding the diagnostic accuracy are the size and location of the lesion, the time elapsed from onset to examination, the use of contrast enhancement and the type of CT scanner used. To further elucidate these aspects, we designed the present study including 300 consecutive patients, all investigated by CT with a 160 x 160 matrix and cerebrospinal fluid spectrophotometry (CSF-SPE). CT indicated a specific diagnosis in 52.7%. In the majority of the remaining cases, additional subclassification was possible by CSF-SPE, emphasizing the complementary information obtained by combined examinations. CT was also found to be a useful tool for reliable prognostic prediction, irrespective of the initial clinical course.
