目的 探究超声联合多排螺旋 CT(MSCT)对早期肝癌诊断的临床价值。方 法 回顾性分析80例早期肝癌患者临床资 料，以细针穿刺活检术或数字血管减影 造影术(DSA)检查结果为“金标准”，分 析超声、MSCT及联合检查对病变特征[假 包膜、肝内动静脉瘘(AVF)、门静脉癌栓 (PVTT)]诊断效果差异。结果 联合检查诊 断假包膜、PVTT准确度均明显高于单纯超 声、MSCT检查，诊断AVF准确度则明显高 于单纯超声检查，差异均有统计学意义(P ＜0.05)；联合检查在诊断病变特征方面 与对应“金标准”一致性均属良好(κ＞ 0.70)。结论 超声联合MSCT应用于早期肝 癌诊断中可获取较多病变特征信息，临床 应用价值较高。

Objective To explore the clinical value of ultrasound combined with multislice spiral CT (MSCT) in the diagnosis of early liver cancer. Methods The clinical data of 80 patients with early liver cancer were retrospectively analyzed. The results of fine needle aspiration biopsy or digital subtraction angiography (DSA) were used as gold standard to analyze the diagnostic effects of ultrasound, MSCT and combined examination on the lesion features [pseudocapsule, arterio-venous fistula (AVF), portal vein tumor thrombus (PVTT)]. Results The accuracies of combined diagnosis in the diagnosis of pseudocapsule and PVTT were significantly higher than those of simple ultrasound and MSCT, and the accuracy in the diagnosis of AVF was significantly higher than that of simple ultrasound (P<0.05). The consistency of combined diagnosis in the diagnosis of lesion features was good with corresponding gold standard (κ>0.70). Conclusion Ultrasound combined with MSCT can obtain more lesion features in the diagnosis of early liver cancer, and it has high clinical application value.
