Abstract
Objective To compare enhanced multi-detector computerized tomography (MDCT)with MRI with Gd-EOB-DTPA in assessing tumor regression after radiofrequency ablation (RFA)after hepatocellular carcinomas (HCC).Methods 34 patients (42 HCCs)from Jau.2012 to Dec.2014 were treated with RFA and underwent enhanced MDCT and MRI with Gd-EOB-DTPA for follow up.Two radiologists reviewed these images and detection of residual or recurrent tumor were assessed.Results 32 nodules were necrotic lesions after treatment,10 showed residual diseases,and 6 new HCCs were identified.At 1 month after RFA enhanced CT has identified 34 necrotic lesions,8 residual diseases and 2 new HCCs.At MRI with Gd-EOB-DTPA instead,31 complete necrotic lesions,11 residual diseases and 6 new HCCS were identified.The sensitivity and accuracy of MRI with Gd-EOB-DTPA in detecting residual diseases were significantly higher than those of enhanced MDCT (All P<0.05)but the difference in the specificity between them was not statistical ( =0.606).The rate of detecting new HCCs of MRI with Gd-EOB-DTPA were higher than that of enhanced MDCT,but the difference was not statistical ( =0.066).Conclusion MRI with Gd-EOB-DTPA is superior to enhanced MDCT in diagnostic accuracy and detection rate of residual diseases or recurrent tumor after RFA.关键词
