Abstract:
0.05 by ? 2 test (? 2=0.487). CT angiography of SSD, MIP, and CT virtual vascular endoscopy could show the location, extent and degree of occlusion or stenosis of internal carotid arteries clearly. CT angiography could also detect calcific plaque in 21 internal carotid arteries and soft plaque in 15 internal carotid arteries. Conclusion Two slices CT perfusion imaging could be made with regular helical CT scanner. CTA could also evaluate the status of plaque. The combination of CT perfusion imaging and CTA are useful not only in observing the morphology of internal carotid arteries, but also in observing the hemodynamic information of the brain, which are important for further general individual analysis.
