目的:动态增强MRI(dynamic contrast-enhanced MRI,DCE-MRI)可以动态地观察病变的血流量、新生血管形成、毛细血管通透性和组织结构等微观情况,而且还可观察肿瘤的强化方式.本研究目的是观察动态增强MRI技术对眼眶肿瘤的定性诊断价值.方法:本研究通过对我院89例经病理证实的眼眶肿瘤进行动态增强MRI检查,获得动态增强曲线(TIC),测出参数Slpre,Slmax,,1分钟强化率(one minute of enhancement ratio,ER1min),最大强化率(maximum of enhancement ratio,ERmax)及最大上升斜率(maximum of slope,Slopemax),清除率(WR)以及Slmax对应的时间Tpeak.结果:动态增强曲线(TIC)的形态以及各参数在眼眶良恶性肿瘤中均有不同的显著性差异.结论:动态增强MRI的检查在临床早期及手术前可以对眼眶肿瘤的性质及预后有一定的预判及诊断价值.
