Computed tomography (CT) is used in diagnosing cerebral diseases, and provides pertinent information, however, lesions seen on the CT appear only with differences in X-ray absorption co-efficient. Therefore, when a diagnosis is attempted regarding lesions without change of density, and a differential diagnosis regarding lesions which do present the same density, information is required concerning pathological characteristics of each disease, clinical histories and other X-ray examinations.In CT, lesions can be detected in the eyes with differential in X-ray absorption, but such is often difficult when there is some relation between the lesions and cerebral structures. Angiograms and pneumo-encephalograms often provide additional information regarding CT.
