The Research Of CT Angiography Technology With64Multi-slice Spiral CT In The Artery Stenosis Of Head And Neck

Objective: to evaluate the64two row helical CT scanningdirection joint for head and neck vascular imaging and post-processing images of vascular score. Methods: to collect70routine optimization parameters of64row helical CT in patients with head and neck angipgraphy, randomly divided into two groups, each group of35cases, under the condition of invariable scan conditions, the group A head to the foot scanning, group B with the foot to the scan head, Using niulti-plane reprganization, curved surface reconstruction, maximuin density projection, volumetric representation, surface cover shows, CT simulation ehdoscopic technique reconstruction image, image reconstruction image respectively by two experienced practitioner and reading independent score. Results: after reconstruction of blood vessel rating: group A: according to the criteria of4points R-CCA/L-CCA/R-IGA/L-ICA/R-VA/L-VA/R-ACA-L-ACA-MCA/L-MCA/R/R-ACP/L-AGP were25,23,23,21,22,24,25,27,?5,26,27,30;3points respectively,10,12,13,11,12,14,10,8,5,9,8,10Group B: accorrding to the grading standard of3ppints-CCA/R-R-CCA/L ICA/L-ICA/R-VA/L-VA/R-ACA-L-ACA-MCA/L-MCA/R/R-ACP/L-AGP were up to23,24,21,23,20,22,23,21,23,27,28,23;3ppints respectively,12,11,14,12,15,13,14,12,8,12,9and12. Conclusion: using the head to the optimization of MSCT in head and neck vascular imaging technology can obtain high quality of cranial neck CTA images and quick, simple and feasible and can provide reliable clinical diagnosis.
