Abstract:
At the Department of internal neurology of Cho Ray Hospital from Dec 2000 to Jan 2003. 130 patients with acute hemisphere cerebral ischemic stroke were studied. Among them, 34 patients could not evaluated by transcranial Doppler sonography, only 79 had transcranial Doppler sonography (TDS) results and MRI results, which confirmed cerebral infarctus. TDS found 30 normal cases, 28 cases with asymmetric indices reduced, 18 cases increased, 1 case of localized acceleration, 2 cases of obstructive cerebral artery in the side of clinical symptom. MRI found 17 normal cases, 62 cases of stricture of cerebral arteries. Sensitivity and specificity of TDS accounted for 74.2% and 82.4% in comparing with cerebro-vascularogramme made by MRI.
