目的 探讨CT与B超在原发性肝癌 首诊中应用价值。方法 回顾性分析2011 年9月-2013年9月经临床病理确诊为原发 性肝癌患者59例，均接受B超、CT检查， 对比检查结果及影像学表现。结果 CT检 查符合率为91.53%显著高于B超76.27%， 结节型病灶的检出率为93.75%显著高于B 超62.5%，均具有统计学意义(P＜0.05)。 B超影像学显示巨块型有低回声区，以圆 形和类圆形为主，结节型病灶为低密度， 无清晰边界；CT影像学显示巨块型和结节 型病灶为低密度，以圆形和类圆形为主， 无清晰边界；部分为不规则，密度均匀或 不均匀；增强扫描结果显示病灶密度增 强，与周围组织有清晰边界。结论 CT诊 断原发性肝癌的准确率较高，可作为首诊 的重要影像学方式。

Objective To investigate the application value of CT and B ultrasound in the initial diagnosis of primary hepatic carcinoma. Methods 59 patients with primary hepatic carcinoma confirmed by clinical pathology from September 2011 to September 2013 were retrospectively analyzed. All of the patients underwent B ultrasound and CT examination. The examination results and imaging findings were compared. Results The coincidence rate of CT examination (91.53%) was significantly higher than that of B ultrasound (76.27%). The detection rate of nodular lesions (93.75%) was significantly higher than that of B ultrasound (62.5%) (P<0.05). B ultrasound imaging showed that the massive type hepatic carcinoma had a low echo area which mainly were round and quasi-circular. The nodular lesions were of low density and without clear boundaries; CT imaging showed that the massive and nodular lesions were of low density and mainly were round and quasi-circular, without clear boundaries; Part of them were irregular and the density was homogeneous or not; The results of enhanced scan showed that the density of the lesion was enhanced and had clear boundaries with the surrounding tissues. Conclusion The accuracy of CT in diagnosis of primary hepatic carcinoma is high and it can be used as an important imaging method for initial diagnosis
