CT Evaluation in Patients with Transient Ischemic Attack

摘要

35 patients clinically diagnosed with transient ischemic attack (TIA) and 15 patients clinically diagnosed with reversible ischemic neurological deficits (RIND) were examined by computerized tomography (CT). 34 of TIA patients showed positive CT scans consisting of small hypodense areas: 60 of RIND patients had larger lesions. In 20 of the overall group the only pathological finding consisted of unilateral focal atrophy or ventricular asymmetry. Correlation between angiographically demonstrated atherosclerotic lesions and positive CT was high. On the contrary, no correlation was found between either the risk factors or the natural history of ischemic attack and positive CT findings.
