64排螺旋CT血管成像技术在头颈部血管病变中的临床应用

目的: 探讨64排螺旋CT血管成像(CTA)技术在头颈部血管病变中的临床应用诊断价值。方法: 选取疑诊为头颈部血管病变患者72例行64排螺旋CTA扫描, 减影后原始扫描数据传入ADW4.4后处理工作站, 采用多平面重建、曲面重建、容积重建、最大密度投影等后处理技术进行重建、分析。结果: 结果发现动脉瘤26例, 动脉狭窄17例, 动脉瘤合并动脉狭窄7例, 血管异常起源8例, 烟雾病5例, 动静脉畸形4例, 正常5例。结论: 64排螺旋CTA能清晰显示各主支血管及其分支, 是一种无创检查方法, 在头颈部血管病变的病因诊断、预后评价中具有较高的临床应用价值, 对临床诊疗起重要指导作用, 可推广应用。

The clinical application of 64 row spiral CT angiography in the diagnosis of craniocervical vascular disease

Objective:To explore the clinical value of 64 row spiral CT angiography( CTA) in the diagnosis of craniocervical vascular disease. Methods:The 64 row spiral CTA in 72 patients with suspected for craniocervical vascular disease were detected,the primary data of which were imported into ADW4. 4 work-station. The craniocervical vessels were analyzed by muti-plane,curved surface and volume reconstruction, and post-processing techniques of maximum intensity projection. Results:Among 72 patients, the cerebral aneurysm in 26 cases,arteriostenosis in 17 cases,aneurysm complicated with artery stenosis in 7 cases,inborn variation of vessel in 8 cases,moyamoya disease in 5 cases,arteriovenous malformation in 4 cases and normal in 5 cases were identified. Conclusions:The 64 row spiral CTA is a noninvasive method,which can clearly display the main artery and its branches,has higher clinical value in the etiological diagnosis of craniocervical vascular disease and prognosis, and play an important guiding role in clinical diagnosis and treatment,can be widely popularized and applied.
