Comparative observation on the result of transcranial doppler and CT angiography in diagnosing intracranial artery stenosis

Objective To evaluate the clinical value of transcranial doppler(TCD)and computed tomography angiography(CTA)in diagnosing intracranial artery stenosis disease.Methods There were 102 cases underwent TCD and CTA examination within two weeks,who highly suspected intracranial artery stenosis.Compared the imaging results of clinical value and analyzed the related factors.Results According to CTA results,the sensitivity of TCD in diagnosing internal carotid artery system vascular stenosis was 87.6%,the specificity was 94.1%,and the coincidence ration was 84.3%.The sensitivity in diagnosing basal arterial vascular stenosis was 73.7%,specificity was 84.3%,and the coincidence ration was 89.2%,compared with CTA results.Conclusion It's reliable to diagnose intracranial artery stenosis with TCD,and the CTA examination provide an effective method for cerebral vascular stenosis disease.The examination of TCD and CTA proved objective clue for cerebral vascular disease each other.
