Imaging of transient ischemic attack / 国际脑血管病杂志

ABSTRACT

The causes of transient ischemic attack (TIA) are diverse and complex.It often attacks repeatedly and its early risk of stroke is high.Identifying etiology and pathogenesis and start the correct treatment in time are the important measures for the prevention of cerebral infarction.However,the conventional CT and MRI reveal no abnormalities in patients with TIA,and it brings difficulties to the clinical diagnosis and treatment.CT perfusion imaging can reflect abnormal cerebral blood flow perfusion in patients with TIA.CT perfusion imaging in combination with CT angiography may visually display its corresponding abnormal changes in the feeding artery and provide the valuable diagnostic information for the location of vascular stenosis,severity,plaque characteristics and collateral circulation.It has very an important significance for guiding clinicians to choose the best treatment options,improve clinic efficiency and observe efficacy.
