Objective To evaluate the diagnostic value of MR diffusion weighted imaging (DWI),DSA,MRA and TCD in the patients with transient cerebral ischemic attack (TCIA).Methods 110 TCIA patients with cervical carotid arteries and vertebral basil arteries system took DWI,DSA,MRA and TCD tests.Results 43% patients with TCIA showed lacunar infarction and 8% of them could show pre early cerebral infarction by DWI which may not be seen by T 2 WI,90% patients showed carotid arteries stenosis and disease relevant cerebral arteritis,48% patients showed stenosis and irregularity of arteries by MRA.100% moderate to severe stenosis/occlusion of internal carotid artery can be shows by TCD.Conclusions DWI and DSA are highly sensitive in the diagnosis of pre early cerebral infarction and stenosis and occlusion of arteries,they are helpful in guiding the therapy of thrombolysis and in evaluating the therapeutic effect,3D TOF MRA could show the abnormalities of 2 3 grade cerebral vessel,TCD has high accuracy rate in moderate severe arteries stenosis or occulusion.
