Abstract:
Objective To evaluate the diagnostic values of MRA,TCD and ultrasonography in carotid territory transient ischemic attacks (TIAs). Methods 42 patients with carotid territory TIAs were examined by MRA, TCD and ultrasonography. Results MRA showed abnormalities of carotid arteries in 12 cases (28.6%) and abnormalities of intracranial arteries in 32 cases (76.2%). 8 cases presented abnormalities both in carotid arteries and intracranial arteries. Abnormalities of intracranial arteries were detected by TCD in 30 cases (71.4%) and abnormalities of carotid arteries were detected by ultrasonography in 16 cases (38.1%).Conclusion MRA, TCD and ultrasonography are useful in the evaluation of etiological factors of carotid territory TIAs.
