Objective To investigate the application of 64 row helical CTVR reconstruction on aneurysm surgery. Methods Imaging data of 63 cases with aneurysm surgery in our hospital from December 2012 to December 2014 were selected and retrospectively analyzed. Patients were examined by 64 row helical CTVR reconstruction and color Doppler ultrasonography before surgery. Compare the different parts tumor neck width、 checkout situation of encephalic angioma and sensitivity, coincidence rate, specific degrees of intracranial aneurysm according to pathological examination results. Results Different parts tumor neck width detected by color Doppler ultrasonography obviously less than pathological examination results (P＜0.05), test results by 64 row helical CTVR reconstruction and pathological examination results had no statistic significance (P＞0.05). Aneurysm detection rate by 64 row helical CTVR reconstruction and color Doppler ultrasonography were 98.51% and 94.03%(P＞0.05), arterial aneurysm specificity by 64 row helical CTVR reconstruction was 93.65%, obviously higher than color Doppler ultrasonography (80.95%) (P＜0.05). Conclusion 64 row helical CTVR reconstruction can clearly shows size, location, tumor neck width of aneurysm tumors. It has high accuracy on arterial aneurysm detection and has guiding significance on program development.
