摘　　要：目的对比分析多层螺旋CT（ MSCT）和MRI评价肝细胞癌（HCC）经导管肝动脉化疗栓塞术（TACE）后肿瘤残留或复发的价值及肿瘤包膜的检出情况。方法对临床确诊的45例HCC患者,经1~5次TACE治疗,并于TACE术后1.5~6.0个月行MSCT及MRI检查。上述检查均在1周内完成,分析和比较MSCT与MRI对HCC患者TACE术后肿瘤残留或复发及肿瘤包膜的检出情况。结果45例患者共计病灶68个,MRI组呈现肿瘤残留或复发的检出率高于MSCT组（ P 〈0.05）；MRI 组的灵敏度以及符合率均高于MSCT组（ P〈0.05）；MRI组显示肿瘤残留或复发的功效与标准组完全一致（Kappa=0.903,P〈0.01）；MRI显示肿瘤包膜的检出率高于MSCT （ P〈0.01）。结论相对于MSCT, MRI能很好地显示肝细胞癌TACE术后局部病灶的活性。Objective To analyze comparatively the clinical value of MSCT and MRI in evaluating the detection of tumor capsule, residual lesion and recurrence of tumor for hepatocellular carcinoma（ HCC） after transcatheter arte-rial chemoembolization（ TACE） with lipiodol and to compare the effectiveness between MSCT and MRI. MethodsForty-five cases with HCC underwent MSCT and MRI within 1. 5~6. 0 months after 1~5 procedures of TACE. All the work was done sequentially within one week. The detection and demonstration of tumor capsule, residual lesion and recurrence of tumor on MSCT and MRI were compared and the results were analyzed. Results 68 lesions were found in 45 patients. The ability of MRI of detecting the residual lesion or recurrence of tumor was superior to MSCT （ P〈0.05 ）;MRI had the sensitivity of 93.48% and consistency rate of 95.59%, which were higher than MSCT（P〈0.05）;MRI was little different as the standard group in detecting the residual lesion or recurrence of tumor （Kappa=0.903,P〈0.01）. Compared with MSCT, MRI had an advantage over detecting tumor capsule（P〈0.01）. Conclusion Compared with MSCT, MRI can well display the activity of lesion for HCC after TACE.
