目的:探讨影响肝动脉造影DSA成像质量的因数。材料与方法:采用西门子数字减影血管造影机(ANGIOSTARPlus DSA),通过285例肝脏动脉造影的摄像全过程,比较并分析成像质量。结果:285例病例均能达到临床诊疗要求,图像清晰、无伪影、完整显示血管及细小病变。结论:影响肝动脉造影DSA成像质量的技术因数,主要包括造影程序、方法、剂量、速率、窗口技术、噪声、术前准备、移动性伪影、技术人员的内在因数等。
Objective: To explore the factors influencing the quality of DSA imaging of hepatic arteriography. MATERIALS AND METHODS: Through the whole process of angiography of 285 cases of liver angiography with Siemens digital angiography (ANGIOSTARPlus DSA), the imaging quality was compared and analyzed. Results: All the 285 cases could reach the clinical diagnosis and treatment requirements. The images were clear and without artifacts. The blood vessels and small lesions were completely displayed. Conclusion: The technical factors influencing the quality of DSA imaging of hepatic arteriography mainly include imaging procedure, method, dose, velocity, window technique, noise, preoperative preparation, mobility artifact, internal factor of technician and so on.
