摘要
目的探讨双能CT(DECT)联合核磁共振(MRI)与原发性肝癌(PHC)患者经肝动脉栓塞化疗(TACE)术后疗效的关系。方法选取我院2015年7月~2019年7月收治的原发性肝癌患者84例为研究对象,采用随机数字表法将患者分为研究组和对照组,各42例。患者经肝动脉栓塞化疗术后4周进行影像学复查。对照组采用MRI复查,研究组采用双能CT联合MRI复查。结果结果显示,研究组的灵敏度、特异度、阳性预测值、阴性预测值和符合率高于对照组,差异有统计学意义(χ^2=12.551、12.827、14.212、16.835、15.445,P<0.05),术后研究组对病灶总数的检出率及对残留或复发病灶的检出率显著高于对照组,差异有统计学意义(χ^2=4.113、7.451、5.628,P<0.05)。两组强化区评分和检出病灶的最大直径无统计学差异(t=1.361、1.199,P>0.05),但研究组可检出的最小直径小于对照组,差异有统计学意义(t=3.726,P<0.05)。结论双能CT联合MRI对原发性肝癌患者经肝动脉栓塞化疗术后病灶的检出率、符合率较高,可在一定程度上降低漏诊、误诊,有较高的推广价值。
Objective To explore the relationship between dual-energy CT(DECT)combined with magnetic resonance imaging(MRI)and curative effects after transcatheter arterial chemoembolization(TACE)in patients with primary liver cancer(PHC).Methods 84 patients with primary liver cancer who were admitted and treated in our hospital from July 2015 to July 2019 were selected as research objects.They were randomly divided into the study group and the control group by random number table method,with 42 cases in each group.The patients underwent imaging review at 4 weeks after transcatheter arterial chemoembolization.The control group was given MRI reexamination,while the study group was given dual-energy CT combined with MRI reexamination.Results The results showed that the sensitivity,specificity,positive predictive value,negative predictive value and coincidence rate of the study group were higher than those of the control group,and the differences were statistically significant(χ^2=12.551,12.827,14.212,16.835,15.445,P<0.05).The detection rate of total lesions and residual or recurrent lesions in the study group were significantly higher than those in the control group,and the differences were statistically significant(χ^2=4.113,7.451,5.628,P<0.05).There was no statistical difference in the score of enhanced regions and the maximum diameter of detected lesions between the two groups(t=1.361,1.199,P>0.05).However,the minimum diameter detected in the study group was smaller than that in the control group,and the difference was statistically significant(t=3.726,P<0.05).Conclusion Dual-energy CT combined with MRI has a higher detection rate and coincidence rate of lesions in patients with primary liver cancer after transcatheter arterial chemoembolization,which can reduce missed diagnosis and misdiagnosis to a certain extent and has a higher promotion value.
