摘要 目的比较CT和MRI诊断肝脏微小转移瘤的敏感性。方法对27例肿瘤肝转移疑似患者行肝脏CT动态增强扫描、MRI平扫和MRI动态增强扫描,有直径≤1 cm的病灶者归入研究对象。按CT平扫+动态增强扫描、MRI平扫、MRI平扫+动态增强扫描3种检查方法,分别计算3种方法诊断肝微小转移瘤的敏感性和阳性预测值。结果27例患者中23例有肝微小转移瘤,共检出117个转移瘤;7例患者28个瘤灶有手术病理结果,其余病灶根据6个月以上的CT或MRI随访得到证实。CT平扫+动态增强扫描、MRI平扫、MRI平扫+动态增强扫描诊断肝微小转移瘤的敏感性分别为75.2%(88/117)、77.8%(91/117)、94.0%(110/117),阳性预测值分别为85.4%、82.7%、97.3%,MRI平扫+动态增强扫描的诊断敏感性和阳性预测值比CT及MRI平扫高,差异有统计学意义(均P<0.01)。结论MRI平扫+动态增强扫描诊断肝脏微小转移瘤敏感性高于CT和MRI平扫,是排除早期肝转移的首选影像学检查方法。
