摘要 目的探讨三维动态增强磁共振血管成像(3DCE-MRA)及彩色多普勒超声(CDFI)检查在下肢血管病变中的应用价值。方法对20例CDFI诊断为下肢血管病变的患者进行下肢血管3DCE-MRA扫描,范围包括肾平面以下腹主动脉、双侧髂内动脉、髂外动脉及股总动脉、股深动脉、股浅动脉、腘动脉、胫前动脉、胫后动脉、腓动脉。其中19例诊断为下肢动脉硬化、斑块形成,1例诊断为外伤后下肢血管损伤。结果20例患者均成功行3DCE-MRA扫描,图像显示清晰,诊断明确。CDFI检出155段病变血管,3DCE-MRA扫描显示病变血管共205段。3DCE-MRA检出病变的阳性率高于CDFI(χ2=14.88,P<0.05)。结论3DCE-MRA以其诊断病变阳性率高,无创性,无辐射,对比剂过敏反应少、肝肾毒性小,可以整体显示感兴趣区血管等优点,在下肢血管病变诊断中应用越来越广泛。
