| 摘 要： | 对胸部增强磁共振血管成像(CEMRA)的序列选择、扫描时机、对比剂剂量和流速、患者配合以及图像后处理等方面的技术优化进行了讨论和分析。认为理想的序列应当快速、多相并有脂肪抑制，延迟时间最好做试验性注射确定，对比剂以30ml、流速2～3ml／s注射为佳，患者良好的配合以及恰当的后处理，都是获得理想检查效果的优化因素。

| Abstract: | The choice of sequence, scanning delay time, dosage and flow rate of contrast medium, patient's cooperation, and post processing of the images were discussed in this article. Fast, multiphase scanning, and fat saturation were required for the best sequence of contrast-enhanced MRI angiography. The delay time should be determined by bolus test injection, 30 ml contrast medium at 2-3 ml/s flow rate were recommended, good cooperation from the patients and felicitously post processing of the images were also necessary for successful examination. |
