CT与MRI在诊断PLC介入术后病灶残留和复发中的诊断价值分析

The Value of CT and MRI in the Diagnosis of Residual and Recurrent Lesions after PLC Intervention

目的:探索CT与MRI在原发性肝癌介入术后病灶残留及复发诊断中的应用。方法:选取某院2017年4月~2018年7月收治的行原发性肝癌介入术治疗患者100例为对象,术后3个月进行CT检查和MRI检查,并以DSA结果为依据,观察CT与MRI的病灶残留检出率、复发检出率等。结果:术后3个月原始病灶残留诊断准确率、复发病灶检出率、新增病灶检出率方面:CT分别为89.12%、44.44%、33.33%,MRI分别为95.92%、77.78%、71.43%,经对比差异均有统计学意义(P<0.05)。结论:在原发性肝癌介入术后病灶残留及复发的诊断上应用MRI价值高,有助于临床医师早期检出病灶残留、复发以及新发病灶,准确评估介入术疗效,为术后治疗提供指导。

Objective:To explore the application of CT and MRI in the diagnosis of residual and recurrent lesions after PLC intervention.Methods:100 patients with primary liver cancer who were treated by interventional surgery from April 2017 to July 2018 were selected as the subjects.CT and MRI examinations were performed three months after the operation.Based on the DSA results,the detection rate of residual lesions and recurrence of CT and MRI were observed.Results:Three months after operation,the accuracy rate of residual diagnosis of original focus,detection rate of recurrent focus and detection rate of new focus were 89.12%,44.44%and 33.33%on CT,and 95.92%,77.78%and 71.43%on MRI,respectively.The difference was statistically significant(P<0.05).Conclusion:MRI is of high value in the diagnosis of residual and recurrence of primary liver cancer after interventional surgery,which is helpful for clinicians to detect residual,recurrent and new focus in the early stage,accurately evaluate the effect of interventional surgery,and to provide guidance for postoperative treatment.
