64排螺旋CT肝动脉血管成像的技术及临床应用

目的探讨分析64排螺旋CT肝动脉血管成像技术特点及临床应用。方法 4组患者采用64排螺旋CT扫描机进行肝动脉血管成像处理及重建处理。结果 VR法进行肝动脉血管成像重建时,370mgI/ml浓度对比剂效果更佳(P【0.05,差异有统计学意义),300mgI/ml浓度对比剂的使用可有效减轻患者不良反应和经济负担、节约资源;采用5ml/s的注射速率相比3ml/s注射速率可得到更优的成像效果。结论一般采用64排螺旋CT肝动脉血管成像急性肝动脉血管呈现扫描及处理时,采用370mgI/ml浓度对比剂可获得更清晰的图像。

Objective To investigate the analysis of 64 row spiral CT angiography of hepatic artery:technique and clinical application of.Methods 4 groups of patients using 64 row helical CT scanning of hepatic arterial vascular imaging processing and reconstruction.Results The method of VR angiography of hepatic artery reconstruction,370mgI/ml concentration of contrast agent is better (P< 0.05,the difference was statistically significant),300mgI/ml concentration of contrast agent use can effectively reduce the adverse reaction and the economic burden of patients,saves resources;adopting 5ml/s injection rate compared to 3ml/s injection rate can get better imaging effect of.Conclusion Using 64 row helical CT angiography of hepatic artery in acute liver artery presenting scanning and processing,using 370mgI/ml concentration of contrast agent can get clearer images.
