多层螺旋CT后处理技术对颈面部血管性病变的诊断价值初探

The value of the multi-slice spiral CT post-processing technique in the diagnosis of the cervical-prosopo vascular diseases

目的:探讨多层螺旋CT后处理技术对颈面部血管性病变的诊断价值。方法:22个颈面部血管异常的病例,行CT增强扫描后以各种后处理技术如VR、MPR、MIP、SSD等方法进行重建。结果:22例颈面部血管畸形,其中动脉瘤6例,动静脉畸形16例,二维和三维图像对病人定位的准确性均较高(86.4%<95.5%)。但在来源血管(45.5%<91.7%)、病变走行(68.2%<100%)、与周围组织的关系(72.7%<100%)等方面,3D重建图像均较2D图像显示出了明显的优势。结论:多层螺旋CT各种后处理技术的综合应用对颈面部血管性病变有较高的诊断价值。

Objective： To explore the value of the multi-slice spiral CT post-processing technique in the diagnosis of cervieal-prosopo vascular diseases.Methods：22 cases with cervical-prosopo vascular diseases were reconstructed using VR,SSD, MPR and MIP after en- hancement. Results：6 eases of aneurysm and 16 arteriovenous malformation were analysed through 2D and 3D images respectively. Both 2D and 3D imaging gave a quite accurate localization for the 22 eases （86.4 % 〈 95.5 % ）, but as to the origin of the affection （ 100% 〉 41.7 % ）, the source of the vascellum （45.5 % 〈 91.7 % ） and the surroundings （2.7 % 〈 100% ）, 3D imagings appeared marked su- periority. Conclusion： Combination of the multi-sllce spiral CT post-processing technique showed high value in the diagnosis of cervical- prosopo vascular diseases.
