摘要 目的:探讨64排螺旋CT冠状动脉成像中,应用双筒注射技术消除上腔静脉伪影的作用。方法:182例疑冠心病的患者行64排螺旋CT冠状动脉成像,采用双筒高压注射器,高速注射对比剂后立刻以相同流率注射30~50ml生理盐水。评价上腔静脉伪影对图像质量的影响,图像质量分优、良和差3个等级。结果:本组中CT冠脉成像质量优者占85%,良占14%,差占1%。结论:通过采用双筒高压注射器,可消除上腔静脉和右心房内潴留对比剂而产生的伪影,提高64排螺旋CT冠状动脉成像质量。 Objective:To study the value of using double tube injector in coronary artery angiography by 64-detector row spiral CT in order to eliminate the artifacts of superior vena cava. Methods: 182 patients had coronary artery angiography with 64-detector row spiral CT,double tube injector was used,flushing with 30~50ml normal saline after injection of contrast medium was undertaken. The image quality affected by the artifacts of superior vena cava was evaluated with the grading system as excellent, good and poor. Results: Image quality graded as excellent, good and poor were 85%,14%,1%, respectively. Conclusion:Flushing with normal saline after injection of contrast medium with double syringe technique, the artifacts produced by contrast medium detained within superior vena cava and right atrium could be eliminated, the image quality of coronary artery angiography by 64-detector row spiral CT could be improved.
