The Relationship between TCD Higher Blood Flow Velocity and Pathology of Internal Cranial Arteries and the Analysis of MRA Results / 中国医学影像技术

PurposeTo investigate the relationship between the TCD higher blood flow velocity and the pathology of internal cranial arteries,so as to improve the veracity of diagnosing cerebrovasculer diseases by TCD. MethodsComparing the blood flow velocity of 84 patients,whose cerebral blood flow are abnormal higher in one or above vessels detected by TCD,with the results of magnetic resonance angiography (MRA). ResultsCerebrovascular stricture,closeness and other diseases are discovered at different parts and to some extent in 80 of above 84 cases according to their detecting results of MRA. ConclusionIt is reliable to diagnose stricture,closeness and other diseases of internal cranial large arteries by TCD higher blood folw velocity.
