摘要
为了探讨声辐射力脉冲成像(ARFI)早期评估微波消融术(PMCT)对原发性肝癌疗效的价值,对我院96个肝癌病灶PMCT术前及术后24小时进行ARFI评估,以术后一个月增强CT(CECT)作为"金标准"对照,结果显示肿瘤消融前后ARFI值有统计学意义(P<0.05),完全灭活组与肿瘤残留组的ARFI值差异有统计学意义(P<0.05)。ARFI值截断点为3.875m/s时,ROC曲线下面积最大。总之,ARFI能早期、定量化反映肿瘤残留,在早期评价微波消融肝癌疗效中有一定价值。
To investigate the early value of acoustic radiation force impulse imaging （ARFI） in percutaneous microwave coagulation therapy （PMCT） of primary liver cancer, a total of 96 lesions diagnosed as primary liver cancer were performed with ARFI both in preoperative and postoperative （24 hours later） observation, compared to contrast-enhanced computed tomography （CECT） which was considered as the gold standard for complete response. ARFI had higher values in postoperative lesions than preoperative lesions which had clinical significance in the test （P〈0.05）. ARFI values of complete response group were higher than those of incomplete response group, while the difference was significant （P〈0.05）. When the cut-off point was 3.875m/s, ARFI in evaluation of incomplete response after PMCT was combined with highest AUC in ROC curve. In a word, ARFI can display direct response of residual tumor timely. As the complement way of CECT, ARFI plays an important role in early evaluation of primary liver cancer in PMCT.
