| 摘 要： | 目的 比较下肢动脉标准三段法3D增强磁共振血管造影(CE-MRA)与小腿及足踝部时间分辨力3D动态增强动脉造影(TR-MRA)对糖尿病足患者下肢动脉狭阻性病变的诊断能力.方法 应用3.0T MR扫描仪对连续检查的29例2型糖尿病并发糖尿病足的患者进行扫描.先对患侧小腿及足踝部行矢状位3D TR-MRA,再行标准自动移床三段法3D CE-MRA从腹主动脉下段扫描至足部,对患侧小腿及足踝部的CE-MRA及TR-MRA两种图像进行评价.将膝以下动脉划分为12节段,对每节段动脉成像质量及小腿静脉污染程度进行3分法评价,应用秩和检验及配对t检验对两种不同成像方法所得评分进行比较.结果 对29条患肢小腿及足踝部动脉血管共348个节段进行了评分.TR-MRA对病变动脉的累计评分为33.17±3.63,显著大于三段法CE-MRA的27.34±4.47(P＜0.001),且CE-MRA对于远段动脉诊断能力呈下降趋势.TR-MRA图像均不受静脉污染影响,平均得分为1.10±0.31,而CE-MRA有13条肢体因静脉污染而影响诊断,平均得分为2.17±0.85,差异有统计学意义(P＜0.001).结论 在CE-MRA明确判断膝以上动脉病变程度的基础上,结合动态TR-MRA,可以避免静脉污染而全面观察小腿及足踝部细小动脉病变. |
