目的:探讨1 6排螺旋CT在椎动脉造影的扫描技术与应用。材料与方法:收集2 2例临床怀疑椎动脉型颈椎病的患者采用西门子1 6排螺旋CT行椎动脉造影检查,应用半透明容积再现漫游(VRT) ,多平面重建(MPR)和最大密度投影(MIP)等技术重建。结果:VRT等重建技术均能够直观清楚地显示椎动脉的形态分布走行情况以及与颈内动脉等相邻血管的位置关系。血管腔的形态及管腔有无狭窄变细,以及狭窄变细扭曲段的长度。并可以显示血管有无钙化等异常。结论:1 6排螺旋CT对椎动脉血管造影检查是一种有效的无创性检查方法,对椎动脉病变有较大的诊断价值
Objective: To explore the technique and application of 1 6-slice spiral CT in vertebral artery angiography. MATERIALS AND METHODS: Twenty-two patients with clinically suspected cervical spondylosis underwent vertebral artery angiography with a 16-slice spiral CT scanner. Transvaginal volume rendering (VRT), multiplanar reconstruction (MPR) and maximum density projection (MIP) and other technology reconstruction. Results: Reconstruction techniques such as VRT were able to directly and clearly show the morphology and distribution of vertebral artery and the position of adjacent blood vessels such as internal carotid artery. The shape of the lumen and the lumen with or without narrowing of the stenosis, as well as narrowing the length of the twisted segment. And can show whether the vascular calcification and other abnormalities. Conclusion: The 16-slice spiral CT is an effective noninvasive method for the detection of vertebral artery angiography and has a great diagnostic value for vertebral artery disease
