摘要
目的研究超声造影(CEUS)联合磁共振成像(MRI)增强扫描早期评价射频消融(RFA)治疗原发性肝癌(PLC)患者疗效的价值。方法2019年1月~2022年1月我院诊治的PLC患者81例,均接受RFA治疗。,在术后1个月进行CEUS和MRI增强扫描检查,以数字减影血管造影(DSA)检查结果为金标准,评判CEUS或/和MRI增强扫描评价的效能。结果在81例PLC患者中,经DSA检查显示61例患者病灶被完全灭活,20例存在病灶残存;CEUS检查显示病灶被完全灭活的灵敏度、特异度和准确率分别为91.8%、85.0%和90.1%,MRI增强扫描评估的灵敏度、特异度和准确率分别为96.7%、95.0%和96.3%,而两者联合评判的灵敏度、特异度和准确率分别为98.4%、100.0%和98.8%。结论在RFA术后,采用CEUS联合MRI增强扫描检查早期评估RFA治疗PLC患者的效果效能高,临床应用价值高。
Objective The aim of this study was to investigate the early evaluation of complete inactivation of tumors by contrast enhanced ultrasound(CEUS)and enhanced magnetic resonance imaging(MRI)scan after radiofrequency ablation(RFA)in patients with primary liver cancer(PLC).Methods 81 patients with PLC were encountered in our hospital between January 2019 and January 2022,and all underwent RFA.One month after the treatment,the CEUS and enhanced MRI scan were performed,and the consistency with digital subtraction angiography(DSA),as the gold standard was compared.Results Out of the 81 patients with PLC,the DSA examination showed the tumor foci was completely inactivated in 61 cases,with tumor residual in 20 cases;the sensitivity(Se),specificity(Sp)and accuracy(Ac)by CEUS evaluation were 91.8%,85.0%and 90.1%,the Se,Sp and Ac by MRI scan were 96.7%,95.0%and 96.3%,and the Se,Sp and Ac by CEUS and MRI combination evaluation were 98.4%,100.0%and 98.8%.Conclusion The early evaluation of tumor inactivation by CEUS and enhanced MRI scan combination after RFA treatment in patients with PLC is efficacious,which might guide the clinicians to make appropriate measures for better outcomes.
