摘要 目的:分析颅内肿瘤诊断中磁共振动态增强的应用效果。方法:收集2017年10月~2018年10月在本院诊治的73例颅内肿瘤患者为研究对象,术前行磁共振动态增强检查,再将诊断结果与术后病理诊断结果进行对比分析。结果:93.15%患者有强化,动态增强信号强度-时间(SI-T)曲线显示,20.59%供血丰富(Ⅰ型)、44.12%供血中等(Ⅱ型)、35.29%供血缺乏(Ⅲ型);脑膜瘤组的平均增强速率(Va)、最大对比增强率(MCER)、增强峰值(SImax)最高,其他肿瘤组到达峰值的时间(Tmax)最高,且组间对比差异呈统计学意义(P均<0.05)。结论:颅内肿瘤诊断中磁共振动态增强的应用,能够获得更多功能定量、形态学信息,辅助判断肿瘤的良性与恶性,以及肿瘤类型,能提升鉴别诊断的准确率,并为手术提供更多参考信息。
