双源CT肝动脉三期扫描对小肝癌的临床诊断价值

Clinical Diagnostic Value of Three Phase Scanning of Hepatic Artery With Dual Source CT for Small Hepatocellular Carcinoma

目的研究双源CT肝动脉三期扫描对小肝癌患者的诊断效果。方法以小肝癌患者40例为研究对象并总结其双源CT动脉三期扫描结果,统计不同分期检查结果中的病灶数量。结果 40例小肝癌患者共检出病灶数量48个,平均直径(2.1±0.4)cm,平扫结果均表现出低密度或者等密度。同时动脉中期、动脉晚期检查强化值与动脉早期相比均增强,差异有统计学意义(P<0.05)。动脉中期、动脉晚期病灶检出率与动脉早期相比均升高,差异有统计学意义(P<0.05)。结论双源CT肝动脉三期扫描对小肝癌患者的病灶诊断有积极帮助,但患者对动脉期的选择要求较高。

Objective To study the effect of three phase scanning of hepatic artery of double source CT on the diagnosis of small liver cancer. Methods 40 cases of small liver cancer were taken as the research object and the results of the three phase of the dual source CT artery were summarized, and the number of the lesions in the results of different stages was counted. Results In 40 cases of small liver cancer, a total of 48 lesions were detected, with an average diameter of （2.1±0.4） cm, and the results of plain scan showed low density or equal density. At the same time, the enhanced value of middle and late arterial examination was enhanced compared with that of the early artery, and the difference was statistically signifcant （P 〈 0.05）. The detection rate of the middle and late arterial lesions was higher than that in the early artery, and the difference was statistically signifcant （P 〈0.05）. Conclusion The three phase scan of the dual source CT liver artery is helpful for the diagnosis of small liver cancer, but the patient＇s choice of arterial phase is higher.
