目的 探讨CT增强扫描在评估原 发性肝癌介入治疗近期疗效中的应用价 值。方法 选取我院2015年4月-2017年1 月的收治的经导管肝动脉化疗栓塞术介 入治疗的38例原发性肝癌患者，患者术 后均进行了CT平扫及增强检查，以数字 减影血管造影(DSA)检查结果为“金标 准”，分析CT增强扫描在评估原发性肝 癌介入治疗近期疗效中的应用价值。结 果 DSA共检出59个病灶，CT平扫共检出 病灶41个(69.49%)，CT增强共检出病灶 58个(98.30%)，CT增强病灶检出率明显 高于CT平扫(P<0.05)，但与DSA检查结 果相比无统计学意义(P>0.05)。CT增强 对≥3cm、<3cm大小的病灶诊断灵敏度 分别为94.44%、97.56%，明显高于CT平 扫(P<0.05)；CT增强对病灶供血动脉来 源诊断灵敏度、特异度均明显高于CT平 扫(P<0.05)；CT增强对合并门静脉癌栓 诊断灵敏度为70.83%，明显高于CT平扫 70.83%(P<0.05)；CT检查显示碘油沉积类 型：完全型9个，缺损型22个，稀疏型11 个，新发病灶17个。结论 CT增强扫描能 有效评估原发性肝癌患者经导管肝动脉化 疗栓塞术介入治疗后的近期效果。

Objective To explore the application value of CT enhanced scanning in evaluating the short-term efficacy of interventional therapy for primary liver cancer. Methods 38 patients with primary liver cancer who received transcatheter hepatic artery chemoembolization for interventional therapy in our hospital from April 2015 to January 2017 were selected. All the patients underwent CT plain scan and enhanced examination after surgery. The results of digital subtraction angiography (DSA) were taken as the "gold standard" to analyze the application value of CT enhanced scanning in evaluating the short-term efficacy of interventional therapy for primary liver cancer. Results A total of 59 lesions were detected by DSA, 41 lesions were detected by CT non-enhanced scanning (69.49%), 58 lesions were detected by CT enhanced scanning (98.30%), and the detection rate of enhanced lesions was significantly higher than that of CT plain scanning (P<0.05), but there was no statistical significance (P>0.05). The diagnostic sensitivity of lesions greater than or equal to 3cm and less than 3cm was 94.44% and 97.56%, respectively, significantly higher than that of CT plain scan (P<0.05). The diagnostic sensitivity and specificity of enhanced CT were significantly higher than that of non-enhanced CT (P<0.05). The diagnostic sensitivity of enhanced CT for complicated portal cancer emboli was 70.83%, which was significantly higher than that of non-enhanced CT (P<0.05). CT examination showed that there were 9 total, 22 defect, 11 sparse and 17 new lesions. Conclusion CT enhanced scanning can effectively evaluate the short-term efficacy of interventional therapy after transcatheter hepatic artery chemoembolization in patients with primary liver cancer.
