目的:探讨16层螺旋CT血管造影在静脉血管方面的应用价值。方法:收集身体不同部位行CT静脉血管造影的病人12例,门静脉血管造影由上肢静脉注入造影剂,静脉血管造影由下肢静脉注入造影剂,行三维重建及多种重建方法处理,分析血管成像质量及诊断价值。结果:图像优质率达97.7%,解剖结构显示清晰,病灶显示准确。结论:多层螺旋CT静脉血管造影有重要的临床应用价值。 Objective: To explore the value of 16-slice spiral CT angiography in venous blood vessels. Methods: Twelve patients with CT venous angiography in different parts of the body were collected. The contrast agent was injected into the upper extremity by portal vein angiography. The contrast medium was injected into the venous vein by veno-angiography. Three-dimensional reconstruction and various reconstruction methods were used to analyze the imaging quality And diagnostic value. Results: The image quality rate was 97.7%, the anatomy showed clearly and the lesions showed accurately. Conclusion: Multi-slice spiral CT angiography has important clinical value.
