| 摘 要： | 目的 探讨心脏支架植入患者做1.5T MRI检查的安全性.方法 24例心脏支架植入患者,植入支架1～3个.支架植入到MRI检查时间最短2 d,最长4年,平均10.6月,其中6例(25%)≤35 d,1例术后2 d进行长达120 min的检查.全部患者在1.5T超导MR上检查.MRI检查时间10 ～120 min,平均30.6 min.检查前、检查后即刻、检查3 d后对生理指标以及身体不适进行记录.检查图像进行质量评估.对3个时间段的数据进行统计学分析,显示呼吸、脉搏、体温、血压数据无显著性差异(P＞0.05).结果 图像质量评估:优良级图像达100%.未发生任何不良反应.结论 心脏支架植入患者行1.5T高场MRI检查是安全的.通常术后4～8周后可行MRI检查,特殊情况可提前检查.
