higher slice
4.RESULTS:The number of MMP-9 po sitive cells increased significantly after cerebral ischemia reperfusion. The num ber of positive cells of 24-hour reperfusion group[(35.81±6.87)/slice] was sig nificantly higher than that of 3-hour reperfusion group[(1.56±1.15)/slice](P< 0.05). The increasing tendency lasted to the 5th day after reperfusion.
6.The coincidence of aneurysms confirmed by operation and those detected by 64-slice spiral CTA was 100%,and the coincidence of digital subtraction angiography(DSA)confirmed with those detected by 64-slice spiral CTA was 97.2.Conclusion The accuracy of 64-slice spiral CTA is higher in the diagnosis of intracranial aneurysm,and it can be used as an important supplement to DSA in the treatment of intracranial aneurysm.
