【摘要】 目的 确定动态增强磁共振成像（DCE- MRI）在评价脊柱肿瘤血供与DSA染色的相关性。方法 40例诊断为脊柱肿瘤的患者在行栓塞术前作MR检查。根据血管造影表现，肿瘤分为富血供组、中等血供组和乏血供组。通过对肿瘤强化区域的感兴趣区（ROI）分析，应用常规MR的强化程度和DCE- MRI参数评价肿瘤血供。结果 40例肿瘤分为乏血供组（16例）、中等血供组（12例）和富血供组（12例）。MRI强化程度在乏血供组和富血供组间没有统计学差异（P>0.05）。而DCE- MRI在两组间显示差异有统计学意义（P<0.01）。而且相对于MRI强化程度，DCE- MRI参数与DSA的关系更加密切。RSlopemax临界值为1.325时预测乏血供肿瘤的特异度和灵敏度最高，分别为100%和87.5%，而临界值为1.85时用于预测富血供肿瘤的特异度和灵敏度最高，分别为100%和96.4%。结论 与常规MRI相比，DCE- MRI可以更准确地评价脊柱肿瘤血供，而且显示与DSA更好的相关性。
