MRI和CT评估原发性肝癌治疗后癌肿残留的应用效果对比观察及价值研究

Comparative Observation and Value Study on the Application Effect of MRI and CT To Evaluate the Residual Cancer after the Treatment of Primary Liver Cancer

目的探讨MRI和CT评估原发性肝癌治疗后癌肿残留的应用效果对比观察及价值。方法选取2017年2月至2018年2月我院收治的130例治疗后的原发性肝癌患者进行研究,按数字表法随机分为对照组(n=65)和研究组(n=65),其中对照组患者采用CT检查,研究组患者采用MRI检查,观察对比两种方法的准确率和敏感性、对治疗后癌肿残留评估的准确率。结果两组患者在性别、年龄、肿瘤结节等方面无统计学差异(P>0.05);研究组肝内病灶阳性率和肝外病灶阴性率显著高于对照组(P<0.05);研究组诊断方法的敏感性和准确率显著高于对照组(P<0.05);患者对对照组诊断方法的满意度明显低于对研究组诊断方法的满意度(P<0.05);治疗3个疗程后对照组诊断方法的准确率明显低于研究组诊断方法的准确率(P<0.05)。结论MRI和CT可用于评估原发性肝癌治疗后复发和残留,MRI检出率显著高于CT。

Objective To explore the efficacy and value of MRI and CT in evaluating the residual cancer after treatment of primary liver cancer.Methods A total of 130 cases of patients with primary liver cancer after treatment in our hospital from February 2017 to February 2018 is studied,according to the digital table method were randomly divided into control group(n=65)and group(n=65),the control group accepted CT examination,research group accepted MRI examination,to observe and compare the accuracy and sensitivity of the two methods,and to evaluate the accuracy of cancer residue after treatment.Results There was no statistical difference between the two groups in gender,age,the size of the tumor nodules.(P>0.05).The positive rate of intrahepatic lesions and negative rate of extrahepatic lesions in the research group were significantly higher than those in the control group(P<0.05).The sensitivity and accuracy of the diagnostic method in the research group were significantly higher than that in the control group(P<0.05).Patients'satisfaction with the diagnostic method of the control group was significantly lower than that of the research group(P<0.05).After 3 courses of treatment,the diagnostic accuracy of the control group was significantly lower than that of the research group(P<0.05).Conclusion MRI and CT can be used to evaluate the recurrence and residual of primary liver cancer after treatment,and the detection rate of MRI is significantly higher than that of CT.
