摘要 胎儿期可发生颅脑缺血或出血等脑血管病变。母体、胎儿、胎盘任一方面出现病理状态，都可能导致胎儿颅脑缺血或出血［1］。胎龄或病变持续时间不同，疾病的表现形式也不同 ［2］。在胎儿期，单纯的颅脑实质缺血比出血更为常见［3］。但因为毛细血管在缺血病变的再灌注过程中可能会破裂，从而导致出血，故缺血和出血也可能混合出现。胎儿颅脑缺血或出血的大部分病例预后欠佳，在产前诊断中早期诊断非常重要。目前，产前超声是诊断胎儿脑血管病变的一线检查方法。但对于某些超声检查不易明确的情况，可选择胎儿头颅磁共振成像（magnetic resonance imaging，MRI）检查，以提高诊断的敏感性和特异性。现对胎儿头颅MRI在诊断颅脑缺血和出血性病变中的价值进行阐述。
