Abstract
Objective To investigate the value of the multi-slice spiral CT perfusion imaging combined with CTA on inter-nal carotid artery stenosis and cerebral infarction. Methods 47 cases with acute cerebral infarction underwent CT perfusion im-aging and CTA examination. Carotid stenosis was evaluated by CTA ,hemodynamic state was assessed by cerebral perfusion images.Results in 47 patients with 94 vessels ,on cerebral infarction side ,carotid artery stenosis detection rate was 64.0%(32/50);on non-infarcted side ,carotid artery stenosis was 29.5% (13/44). Carotid artery stenosis detection rates of two sides were significantly different (P<0.05). In 47 cases of cerebral infarction ,cases with large ,medium and small size of in-farction were 9 cases ,20 cases and 18 cases respectively. There are 45 vessels with varying degree stenosis in 94 vessels ,mild , moderate and severe stenosis were 17 cases ,16 cases and 9 cases respectively ,3 cases of patients with vascular occlusion. The coincidence of carotid artery occlusion and the large volume of infarction was 100% (3/3);The coincidence of severe stenosis and the large volume of infarction was 67% (6/9);moderate stenosis and the volume of infarction 81% (13/16);mild stenosis and the small volume of infarction 88% (15/17) ,the difference was statistically significant (P<0.05). Conclusion Multislice spiral CT cerebral perfusion imaging combined with CTA is able to evaluate the relationship between the degree of carotid ste-nosis and cerebral infarction.关键词
