VCTDSA Combined with CT Perfusion Imaging in the Diagnosis of Acute Ischemic Stroke Using Inquiry

Objective:To explore the 64-slice volume CT digital subtraction angiography(the Volume computed tomography digital subtraction angiography,VCTDSA) combined with CT perfusion imaging in the diagnosis of acute ischemic stroke value.Methods:Retrospective analysis of 45 patients with clinically diagnosed as clinical data of patients with acute ischemic stroke,respectively to give VCTDSA and CT perfusion imaging processing,and analysis of diagnostic sensitivity and specificity of these two technologies in patients with acute ischemic stroke.Results:45 patients check intracranial bleeding lesions in different parts,more common in the ventricles,are associated with varying degrees of abnormal vascular network formation,which VCTDSA image quality is superior to CT perfusion imaging,VCTDSA than DSA can accurately display and measurement of arteriovenous fistulathe size,VCTDSA,and MRA was no significant difference in tumor long axis,the comparison of the aneurysm neck.Conclusions:The other subtraction CTA VCTDSA combined with CT perfusion imaging in the diagnosis of acute ischemic stroke patients have an advantage.
