目的：分析16层螺旋CT脑血管造影技术在临床的应用价值。方法：回顾性分析43例怀疑脑血管疾病患者CT血管造影(CTA)的影像资料，后处理技术采用容积再现(VR)成像、最大密度投影(MIP)和多平面重建(MPR)技术进行三维重建后处理。结果：影像资料显示，在43例患者中动脉瘤6例，动静脉畸形1例，动脉狭窄8例，先天发育异常1例，未见血管异常27例。43例脑血管图像质量分析对脑血管主干及其主要分支显示100%，并且清晰显示动脉瘤的位置、形态、大小以及与周围血管和颅骨的关系，同时清晰显示畸形血管团、供血动脉和引流静脉。结论：16层螺旋CT血管造影成像技术具有安全、快速、基本无创及图像清晰的特点，可作为脑动脉病变有效的首选诊断方法。

Objective: To analyze the clinical value of 16-slice CT angiography techniques in cerebral artery lesions. Methods:Forty three cases in our hospital with suspected cerebrovascular disease who performed computed tomography angiography were retrospectively analyzed. Volumetric imaging, maximum intensity projection and multi-planar reconstruction technique for three-dimensional reconstruction process were used in post-processing. Results:There were 27 cases with no abnormal blood vessels, 6 cases with aneurysm, 1 with arteriovenous malformation, 8 with arterial stenosis and 1 with congenital abnormalities. The image quality analysis of cerebral vascular trunk and main branches was 100%performed in 43 cases. The location, shape, size, and the relationship with the surrounding blood vessels and skull of the aneurysm have been clearly shown, and the nidus, feeding arteries and draining veins have also been clearly shown. Conclusion:With the features of safe, fast, non-invasive and clarity in images, 16-slice CT angiography imaging technology can be used as the first choice of screening cerebral arterial disease.
