目的 探究超声/电子计算机断层 扫描(CT)融合成像技术在常规超声难显 示的肝癌中的应用效果。方法 回顾性分 析我院经CT清晰显示而二维超声未提示的 102例肝脏局灶性病变患者临床资料。记 录102例患者病理结果，并分析低年资医 师(工作年限＜3年)及高年资医师(工作年 限＞10年)应用超声/CT融合成像技术的融 合情况及对肝癌的诊断效果。结果 102 例肝脏局灶性病变患者中原发性肝癌86 例，肝血管瘤10例，肝血管内皮细胞瘤5 例，肝结节增生1例。低年资医师及高年 资医师融合成功率均为100%，且其对位误 差比较，差异无统计学意义(P＞0.05)。 低年资医师与高年资医师超声/CT融合成 像诊断正确率比较，差异无统计学意义(P ＞0.05)。结论 超声/CT融合成像成功率 高，且不受人为因素的影响，还能辅助诊 断原发性肝癌，具有实时、简便、稳定等 优点。

Objective To explore the application effects of ultrasound/computed tomography (CT) fusion imaging in the treatment of liver cancer difficult to display by conventional ultrasound. Methods The clinical data of 102 patients with focal hepatic lesions were visualized clearly by CT and not indicated by two-dimensional ultrasound were analyzed retrospectively. The pathological results of 102 patients were recorded, and the fusion conditions of the junior physicians (working years <3 years) and the senior physicians (working years >10 years) who used ultrasound/CT fusion imaging technique and the diagnostic effects of liver cancer were analyzed. Results Among 102 patients with focal hepatic lesions, there were 86 cases of primary liver cancer, 10 cases of hepatic hemangioma, 5 cases of hepatic vascular endothelial cell tumor and 1 case of liver nodular hyperplasia. The fusion success rates of the junior physicians and the senior physicians both were 100%, and there was no statistically significant difference (P>0.05). There was no significant difference in the diagnostic accuracy of ultrasound/CT fusion imaging between the junior physicians and the seniorphysicians (P>0.05). Conclusion Ultrasound/CT fusion imaging has high success rate and was not affected by human factors. And it can also assist in the diagnosis of primary liver cancer, and it has the advanteges of real-time, simple and stable.
