Aim To investigate the diagnostic values of magnetic resonance angiography (MRA), color Doppler ultrasonography and Transcranial Doppler (TCD) in patient with Transient ischemic attacks (TIA). Methods 90 patients with TIA were examined by MRA, color Doppler ultrasonography and TCD. Results MRA showed 76 patients had intracranial or extracranial arteries stenosis or occlusion. 27.8% (25/90)of the cases had either extracranial artery stenosis or occlusion. 24.4% (22/90)of the cases had either intracranial artery stenosis or occlusion. 32.2% (29/90)of the cases had multiple intra-and extracranial arteries stenosis or occlusion. In ICA-TIA group, there were much more cases had only intracranial artery stenosis or occlusion than VB-TIA group (P<0.01). However, there were fewer cases with multiple intra-and extracranial arteries stenosis than VB-TIA group (P<0.05). There were almost equal cases with extracranial arteries stenosis in both group. In general, there were more patients with extracranial arteries stenosis or occlusion than intracranial arteries (54.1% vs 45.9%). In ICA-TIA group, there were slightly more intracranial arteries stenosis than extracranial arteries (53.3% vs 46.7%). However, there were much more extracranial arteries stenosis than intracranial arteries (64.1% vs 35.9%) in VB-TIA group. The difference was significant (P<0.05). Carotid or vertebral arteries stenosis or occlusion were detected by color Doppler ultrasonography in 45 cases and 73 cases were found to have plaques. Carotid arteries stenosis or occlusion were detected by MRA, color Doppler ultrasonography. Abnormalities of intracranial arteries were detected by TCD in 72 cases (80%). Conclusion MRA, color Doppler ultrasonography and TCD are useful in the evalution of etiological factors and must be examined to guide the treatment for patients with TIA.
