目的 探讨双源CT双能量扫描在诊断肝脏肿瘤中的临床应用价值。方法 选取2013年6月-2014年5月在该院行双源CT 双能量扫描的50例肝脏肿瘤患者的临床及影像资料进行分析研究。结果 针对患者选择的扫描方式不同，对比患者 肝脏、脾脏、腹主动脉、肌柱后方肌肉TNE与VNC CT值，二者间的差异无统计学意义(P＞0.05)，原发性肝癌在实质 期碘基图像上的二者数值分别低于肝血管瘤、胆管细胞癌,差异具有明显统计学意义(P<0.05)。结论 双能量扫描在 诊断肝脏肿瘤中具有潜在的临床应用价值，应得到推广使用。

Objective The Thesis aims to probe into the Clinical application value of dual-source CT’s dual energy scanning in the diagnosis of liver tumor. Methods We have took a comprehensive researches and analysis on the clinical image data of 50 liver tumor patients under the dual-source CT’s dual energy scan during the period of June 2013 to May 2014 in our hospital. Results With the analysis of different scan ways picked by the patients, and comparison with the value of TNE and VNC CT of the liver spleen aorta abdominalis Muscle behind muscles, it shows the difference between the two is not statistically significant(P>0.05). The value of primary carcinoma of liver related with TNE and VNC CT which is reflected on the substantial iodine density image is lower than that of hepatic hemangioma and cholangiocellular carcinoma, however, the difference is statistically significant. Conclusion Dual energy scanning has the potential Clinical application value in the diagnosis of liver tumor, which should get a big promotion and application.
