摘要 目的 :评价磁共振增强血管造影(CEMRA)对胸部疾病的临床应用价值。材料和方法 :应用1.5T成像系统 ,以30ml磁共振造影剂和3ml/s流速对40例临床疑诊胸部疾病的病人进行动态增强MR血管造影 ,评价其临床应用价值。结果 :以30ml剂量和3ml/s的速度在95 %的病人中可获得良好的胸部CEMRA图像。40例病人除了常规图像提供的诊断信息外 ,CEMRA上33例有不同程度的心血管结构或功能方面的异常。结论 :以30ml剂量和3ml/s流速在95 %的病人中可获得满意的CEMRA图像 ,并能清楚显示血管性异常 ,解决临床的需求。 Purpose:To evaluate the clinical use of contrast-enhanced MR angiography(CEMRA) in thoracic diseases.Materials and Method:40 patients suspected of thoracic diseases were examined with CEMRA(30ml of contrast medium and 3ml/s flow rate).Results:95% of the CEMRA images were good enough for evaluation.In addition to the informations provided by the conventional images,morphological or functional abnormalities of hearts and vessels were found in 33 patients on CEMRA images.Conclusion:The quality of CEMRA images was satisfied in 95% patients by using 30ml contrast agent and 3ml/s flow rate.The abnormal features of vessels in thoracic diseases could be displayed clearly.
