【摘要】：目的探討應(yīng)用CEUS評(píng)估多電極冷循環(huán)射頻消融(RFA)治療小肝癌后腫瘤滅活程度的價(jià)值。方法對(duì)49例小肝癌患者(63處病灶)RFA治療前后分別進(jìn)行常規(guī)超聲、CEUS檢查及增強(qiáng)CT檢查,評(píng)估病灶完全消融及局部殘留情況。結(jié)果 RFA治療前,CEUS測(cè)量病灶最大徑為(2.47±0.53)cm,常規(guī)超聲測(cè)值為(2.12±0.57)cm,二者差異有統(tǒng)計(jì)學(xué)意義(t=-4.907,P0.05)。CEUS測(cè)量病灶面積為(6.50±1.26)cm2,常規(guī)超聲測(cè)值為(5.43±1.06)cm2,差異有統(tǒng)計(jì)學(xué)意義(t=-6.867,P0.05)。CEUS與增強(qiáng)CT對(duì)病灶檢出率差異無(wú)統(tǒng)計(jì)學(xué)意義(χ2=0.25,P0.05)。RFA治療后,CEUS判斷腫瘤完全滅活與局部殘留情況與增強(qiáng)CT差異無(wú)統(tǒng)計(jì)學(xué)意義(χ2=0.50,P0.05)。結(jié)論 CEUS可用于評(píng)估小肝癌RFA治療效果。
[Abstract]:Objective to evaluate the value of CEUS in the evaluation of tumor inactivation after multi-electrode cold circulation radiofrequency catheter ablation (RFA) for small hepatocellular carcinoma (HCC). Methods 49 patients with small liver cancer (63 lesions) were examined by conventional ultrasound CEUs and enhanced CT before and after RFA treatment to evaluate the complete ablation and local residual of the lesions. Results before RFA treatment, the maximum diameter of lesions measured by CEUs was (2.47 鹵0.53) cm and that by conventional ultrasound was (2.12 鹵0.57) cm. There was a significant difference between CEUS and enhanced CT in detecting lesion area (6.50 鹵1.26) cm ~ (2) and conventional ultrasound (5.43 鹵1.06) cm ~ (2), respectively. There was no significant difference in the rate of tumor inactivation and local residual after RFA treatment (蠂 2 / 0.25 P 0.05). There was no significant difference between CEUs and enhanced CT (蠂 2 / 0.50 P 0.05). Conclusion CEUS can be used to evaluate the efficacy of RFA in the treatment of small hepatocellular carcinoma.
