摘要 目的:研究动态增强磁共振成像技术(LAVA)在肝脏占位检出和定性诊断中的价值。方法:对肝脏占位性病变44例,结合穿刺及B超、CT等综合影像分析结果,与普通扫描结果进行对比,两名医生在不了解最后诊断的条件下,回顾分析全部病例的平扫及LAVA动态增强MRI检查资料,统计检出率和定性诊断肯定率。结论:在89个肝占位(≤3 cm),动态增强MRI的检出率(动脉期+门脉期,98.9%)和平扫MRI(T1W I+T2W I,92.3%)相比差异显著(P<0.05);平扫联合动态增强的定性诊断肯定率(91.2%)较单纯平扫(75.8%)有明显提高(P<0.01)。结论:动态增强MRI是提高肝占位检出和定性诊断的有效方法,能为肝脏占位性病变的定性诊断提供重要依据。
