摘　　要：目的探讨64层螺旋CT血管造影(CT angiography,CTA)对颅内动脉瘤的诊断价值。方法41例颅内动脉瘤患者行64层螺旋CT增强扫描。用高压注射器经肘正中静脉注射对比剂(碘海醇,350 mgI/mL)100 mL,注射速率3 mL/s。在工作站上对原始数据进行重建,包括容积重建、曲面重建、多平面重建、最大密度投影和表面覆盖成像。结果41例患者检出47个动脉瘤。结论64层螺旋CTA是诊断颅内动脉瘤的安全、快速、无创、有效的方法,为临床治疗提供依据。Objective To explore the diagnostic of intracranial aneurysms with 64 slice spiral CT angiography （CTA）. Methods Forty-one cases with intracranial aneurysms were examined with enhanced 64 slice spiral CT. and injected with contrast medium （iohexol, 350 mgI/mL） 100 mL through medial cubital vein with high pressure syringe at 3 mL/s velocity. Then the initial data were reconstructed with workstation, including volume rendering, curved planar reformation,multiplanar reformation,maximum intensity projection and shaded surface display. Results Forty-seven aneurysms were detected in 41 cases. Conclusion 64 slice spiral CTA is an safe, quick,non-invasive and effective method in diagnostic of intracranial aneurysms, and offer evi dence for clinical treatment.
