| 摘 要： | 目的讨论三维16层螺旋CT血管造影术（3D—CTA）诊断及评价颅内动脉瘤的应用价值，并与数字减影血管造影术（DSA）进行对比研究。方法对怀疑颅内动脉瘤的76例蛛网膜下腔出血患者（其中男性35例，女性41例，年龄38～83岁，平均年龄60．5岁）行3D-CTA检查及DSA检查。重建方法采用多平面重建（MPR）、最大密度投影（MIP）和容积透视（VR）等。通过3D-CTA确定动脉瘤的数目、位置、大小、与周围血管关系及是否有血栓和钙化等信息，并与DSA对比评价3D-CTA诊断动脉瘤的敏感性及特异性。结果3D—CTA共发现62例患者的68个动脉瘤，根据DSA的检查结果，发现1例动脉瘤被3D—CTA漏诊。在位置、大小等方面，3D—CTA与DSA及手术所见有较高的一致性，而3D—CTA显示空间征象、血栓和钙化的能力明显高于DSA。结论3D—CTA对颅内动脉瘤具有高度的敏感性和特异性，快捷、无创，可代替DSA来进行筛查及术前评估颅内动脉瘤。

| Abstract: | Objective To evaluate the value of the three-dimensional 16-slice spiral computed tomography angiography (3D- CTA) in the detection and characterization of intracranial aneurysm, and compare with digital substraction angiography (DSA). Methods Seventy-six patients (male 35, female 41, aged 38 - 83 years, mean age 60.5 years) with subarachinoid hemorrhage(SAH) suspected intracranial aneurysm were performed 3D-CTA and DSA. 3D postprocessing included multiplanar reconstruction(MPR), maximum intensity projectio... |
