摘　　要：目的探讨双容积重建技术在颅内动脉瘤弹簧圈栓塞术中的应用价值。方法对2012年6月-2013年4月收治的20例行颅内动脉瘤弹簧圈栓塞术患者的三维造影数据进行双容积重建,从弹簧圈的检出率,动脉瘤的栓塞程度,术前、术后动脉瘤瘤颈和瘤体长度,重建图像特点和应用价值等方面对双容积重建的作用进行评价。结果双容积重建共检出弹簧圈缠绕团20个,检出率100%。20例中有13例动脉瘤无造影剂渗入,3例瘤体内有造影剂占位,4例可见瘤颈有造影剂占位。术后瘤颈、瘤体长度与术前比较有所改变,但差异无统计学意义(P>0.05)。双容积重建影像能显示出弹簧圈缠绕团、血管、颅骨和融合图像,可根据临床需要选择不同的影像模式来显示动脉瘤。结论双容积重建技术能提供弹簧圈缠绕团定位、栓塞程度、动脉瘤长度等信息,并可通过多种影像模式评估栓塞效果,在动脉瘤的介入栓塞术中具有较高的应用价值。Objective To explore the value of dual volume reconstruction technique in Guglielmi detachable coil （GDC） embolization ofintracranial aneurysms. Methods Three-dimensional imaging data of 20 patients received GDC embolization of intracranial aneurysms from Jun. 2012 to Apr. 2013 were analyzed for dual volume reconstruction. The value of application of dual volume reconstruction was evaluated by the detection rate of coils bolus, degree of aneurysm occlusion, the length of aneurysm sac and aneurysm neck before and after embolization, and the characteristics and clinical value of the reconstructed images. Results A total of 20 coil boluses were detected by dual volume reconstruction images, and the detection rate was 100%. Among all of 20 patients, no visualization of contrast medium in the aneurysm was found in 13 patients, while contrast agent was found in the aneurysm sac in 3 patients and in the aneurysm neck in 4 patients. The length of aneurysm neck and sac was somewhat changed before and after embolization with no statistically significant difference （P〉0.0S）. The dual volume reconstruction could reveal coil bolus, vessels, cranium and fusion images, and the aneurysms could be shown by different imaging modes according to the clinical requirement. Conclusion Dual volume reconstruction technique can display the location of coil bolus, degree of occlusion and aneurysm size, and evaluate the embolization effect by multifarious imaging modes, providing a great deal of information for the evaluation of GD C embolization of intracranial aneurysm.
