目的: 探讨磁共振检查在诊断胎儿侧脑室内陈旧性出血中的意义。方法: 对比分析侧脑室内陈旧性出血组(41例)与单纯性侧脑室增宽组(65例)胎儿侧脑室增宽的程度及其对称性、产后发育情况之间的差异。结果: 单纯性侧脑室增宽组主要为对称性增宽(45/65, 69.2%), 侧脑室内陈旧性出血组侧脑室增宽主要为非对称性(20/65, 30.8%); 单纯性侧脑室增宽组胎儿产后发育正常的比例(61/65, 93.8%)明显高于侧脑室内陈旧性出血组胎儿(29/41, 70.7%), 差异有统计学意义(P < 0.05);两组病例侧脑室增宽程度差异无统计学意义(P=0.444)。结论: 磁共振检查在胎儿侧脑室内陈旧性出血的诊断以及产后发育情况评估中具有重要意义。
