Abstract
为探讨磁共振成像(MRI)和B超对卵巢肿瘤良恶性鉴别、定性及恶性肿瘤分期的诊断价值。采用双盲法对42例(49个病灶)均经手术、病理证实的卵巢肿瘤的MRI及B超征象进行分析。计算各自的敏感性、特异性、准确性、并进行比较。表明MRI和B超对卵巢肿瘤良恶性鉴别的敏感性、特异性、准确性分别为88.1%/61.90%、95.2%/71.43%、91.67%/66.67%,两者间存在显著差异(P<0.05),定性准确性分别为80.96%和52.38%(P<0.05),对恶性肿瘤的分期MRI准确性达77.80%。显示MRI扫描对卵巢肿瘤良恶性鉴别、定性均优于B超,对恶性肿瘤的MRI分期亦有较大价值。当然,MRI目前尚存在检查费用高、时间长、实时性较差以及对某些肿瘤的组织定性有一定限度,有待进一步探索和改进
