摘要:【摘要】目的探讨MRI弥散加权成像(DwI)与动态增强扫描(DCE)序列联合应用在肝细胞癌(HCC)患者手术切除术后检出复发微小肝癌(mHCC)的诊断价值。方法在43例肝细胞癌患者手术切除术后行MRI、DWI和DCE扫描序列,以早期发现复发癌灶。结果在术后1年,43例HCC患者中发现54个复发病灶;DWI联合DCE对复发的mHCC判断的敏感性、特异性和准确性分别为89.5%、97.1%和94.4%,DCE单独诊断的敏感性为63.2%,特异性为88.6%,准确性为79.6%,而DCE单独诊断复发mHCC的敏感性,特异性和准确性最低,分别是60.O%,67.7%和64.8%(P〈O.05)。结论在MRI检查中应用DWI和DCE扫描序列联合检测能显著提高对复发的mHCC的发现率。
