PDFAbstract
Objective To explore the reliability of TCD in the diagnosis of anterior circulation stenosis. Methods Acute cerebral infarction patients who met the inclusion criteria as well as received TCD and CTA inspection were recruited. The test results of TCD and CTA were compared. Results TCD testing corresponding anterior circulation stenosis is not statistically different witrh CTA, they have a good consistency. The accuracy of TCD in testing the MCA blood vessels is the highest. The coincidence rate of TCD in diagnosing moderate and severe MCA stenosis was higher than that of mild stenosis. Conclusions 1. For the diagnosis of anterior circulation stenosis, TCD and CTA results are no statistically different. 2. The accuracy and sensitivity of TCD is the highest applying on MCA. 3. The coincidence rate of TCD in diagnosing moderate and severe MCA stenosis was higher than that of mild stenosis.
