头颈部数字减影CT血管成像技术探讨

目的：探讨头颈部数字减影CT血管成像（DSCTA）成像技术的方法。方法：随机选择12例作头颈部脑血管DSCTA病例,通过扫描前训练、缩短扫描时间以减少患者运动,取得增强前后位置一致的横断图像。采用CT机自带的软件进行图像减影处理。采用减影后的图像进行三维后处理。结果：12例患者头颈部血管减影成功,取得了良好血管减影图像。结论：科学的DSCTA检查技术可获得良好的头颈部血管性病变减影图像。

Digital Subtract CT Angiography Technology of Head and Neck

Objective： To explore the Digital Subtract CT angiography （DSCTA） imaging method for head and neck. Methods： Twelve cases who needed head and neck cerebral vascular DSCTA were randomly selected. The patient＇s movement was controlled by pre-scan treatment and shortening of scan time so as to acquire same cross-sectional images before and after enhancement as possibly as we could. Image processing subtraction was done by the soft-ware equiped in the CT machine and three-dimensional images of post-treatment were based on these subtraction images. Results： Twelve patients with head and neck vascular subtraction achieved good blood vessels by video images successfully. Conclusion： DSCTA will be useful in the head and neck vascular lesions by video images.
