[(Negative) CT findings in subjects with ischaemic strokes (author's transl)]

50 subjects who had one or several ischaemic attacks without detectable attenuation area in the CT scan were examined. CT findings grouped as follows: normal, cortical generalized atrophy and cortical localized atrophy with or without ventricular or cysternal enlargement, diffuse cortical and ventricular atrophy. The relationships between CT scan, clinical evolution, number of ischaemic attacks and predisposing risk factors were also considered. The mainly morphological value of CT and the limited dynamic and functional aspects of this technique are emphasized in agreement with other authors.
