摘要
目的分析实时透视触发三维增强磁共振颈部血管造影技术关键因素,揭示该技术达到成功率100%的关键所在。方法回顾性分析2012年1月至2012年3月期间完成的47例实时透视三维增强磁共振颈部血管成像,根据制定的分级标准评判图像质量,探讨该成像技术的方法并评价其临床应用效果,根据结果,分析该造影成功的关键因素,寻找造影失败和造影质量不佳的原因,改进后完成11例,再次观察分析造影结果。结果 47例实时透视三维增强磁共振颈部血管成像,其对颈部一至四级血管的显示优秀者(4分)27例,占比57%,良好者(3分)13例,占比28%,两者共40例,显像优良率占比85%,中等者(2分)3例,占比6%,差者1例,占比2%,失败者(0分)3例,占比6%。。而改正造影方法后的11例,全部达到4分标准,经统计学检验,与改进前相比P<0.05,有显著差异,证明该改进措施正确有效,是该造影技术成功的关键所在。结论掌握了实时透视触发三维增强磁共振血管造影技术的该项关键因素,可获得造影100%的成功率,且操作简便易行,显像效果优秀,在颈部血管病变的影像诊断中应能得到广泛的推广应用。
Objective To discuss the key factor of three Dimensional Contrast Enhanced Magnetic Resonance cervical angiography with real-time fluoroscopic triggering, and ,＇e- veal the key of this technology to achieve 100% success. Methods Retrospective analysis 47 cases of three dimensional contrast enhanced Magnetic Resonance angiography with real-time fluoroscopic triggering in carotid arteries, completed by Nanjing hospital of tradi- tional Chinese medicine fi＇om January 2012 to Mz, rch 2012, to evaluate the image quality according to grading standards made by etc., and discuss the way of this imaging techniques,analysis the clinical application. According to the results, analysis the critical factors of the successful imaging, looking for the reason of failure imaging and worse quality imaging, alter the improvement in 11 cases, again observe and analysis the imaging results. Results In these 47 cases of three dimensional contrast enhanced Magnetic Resonance cervical angiography with real-time fluoroscopic triggering, the 27cases showed the 1 to fot, r grade carotid arteries very well （4 scores）. 57%. 13 cases well（3 scores）, 28%, the both is 85%, 3 cases showed medium（2 scores）, 6%, 1 cases is bad（l sco,＇es）, 2%, and 3 cases are failure, 6%. And the 11 cases with correct imaging method are all 4 points standard, the statistical test of improved than before： P 〈 0.05, it is significant difference, prove that the improvement measures is correct and effective, and it is the key to the success of imaging technology. Conclusion Master the key factors of the real-time per- spective trigger 3 d enhanced magnetic resonance cervical angiography technology, may obtain imaging 100% success rate, and the operation is simple, convenient and feasible, imaging effect is very well, in the cervical vascular lesions image diagnosis, it should be able to get the extensive expansion application.
