摘　　要：目的分析64排螺旋CT容积再现(volume rendering,VR)重建技术在动脉瘤夹闭术中的应用。方法回顾性分析我院2012年12月至2014年12月63例行动脉瘤夹闭术患者的影像学资料,患者在手术前均先进行64排螺旋CT VR重建技术检查和彩色多普勒超声检查,以病理检查结果为标准,比较两种检查方式检出的不同部位瘤颈宽度、不同部位脑血管瘤检出情况以及检查颅内动脉瘤的灵敏度、符合率、特异度。结果彩色多普勒超声检查检查不同部位瘤颈宽度显著小于病理检查结果(P<0.05),而64排螺旋CT检查结果与病理检查无统计学意义(P>0.05);64拍螺旋CT动脉瘤检出率为98.51%,彩色多普勒超声检查检查的检出率为94.03%(P>0.05);64排螺旋CT检查动脉瘤的特异度为93.65%显著高于彩色多普勒超声检查80.95%(P<0.05)。结论64排螺旋CTVR重建技术能准确清晰的显示出动脉瘤瘤体的大小、位置、瘤颈宽度等指标,对动脉瘤的检出准确性高,对动脉瘤夹闭术的方案制定有重要的指导意义。Objective To investigate the application of 64 row helical CTVR, reconstruction on aneurysm surgery. Methods Imaging data of 63 cases with aneurism 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 befi）re 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.
