Abstract: Objective To use the multi-slice CT(MSCT)cerebral perfusion imaging and CT angiography(CTA)in the clinical diagnosis of transient ischemic attack(TIA).Methods 20 cases with transient ischemic attack within 48 h were examined with 16-slice CT perfusion imaging(CTPI)and CTA in head and neck.The interesting regional cerebral blood flow(rCBF),cerebral blood volume(rCBV)and the time to peak(rTP)were analyzed.Results The rTP of affected side delay compared with that of the healthy(t=3.04,P=0.008).CTA showed the responsible vascular stenosis or occlusion in varying degrees.There was not significant correlationship between rTP and vascular stenosis(r=0.32,P=0.17).Conclusion Cerebral perfusion imaging and head and neck CTA can provide valuable information for diagnosis and treatment of TIA.
